I always put a m before the foursquare domain like this. That works too.

it converts the address to this after you click it.

It also works for these venue links too. https://m.foursquare.com/venue/110555

Foursquare gives homes more privacy:

http://aboutfoursquare.com/a-house-is-not-a-home-foursquare-gives-homes-more-privacy/

Adding your home on foursquare has always been a dicey proposition in terms of privacy. Once you became mayor it showed on your profile with a pin pointing directly to it. If you added the address, it showed up right there on the page, making it easy for anyone to find exactly where you lived. Even if you took the trouble to create the location away from your home, it was still easily found by superusers since they could just track the pattern of checkins based on the blue dots.

Late last week foursquare quietly rolled out a change that makes your home much more private — as long as it’s properly categorized. Once categorized as a home, venues now show a message that says: Since this is a home, the exact location is not shared here. This map is of the approximate area.

The map pin disappears and the map is centered on a random spot at least one-quarter mile away from the actual location so it’s no longer easy to tell exactly where the house is. The street address is hidden, with only the city, state and zip visible. Even the superuser loophole has been closed; blue checkin dots no longer show up for superusers."
Venue owners and their friends can still see the address and correct pin location when logged in. Users who find that their home is on foursquare but isn’t categorized properly can use the new “Report a Problem” link to report it to foursquare staff and get it categorized properly.

in my family, we are 4sq users... but there is one think I cannot understand.
different account don't behave the same way:
- we don't have the same amount of max check a day (1 account can check 30 times a day, another 50 a day and another 39 a day.) (we made the test: with iphone 4 & 4S/android galaxy S.. using account on a phone then another, it's really account depending not linked to the type of phone or apps version)
- we don't have the same amount of max check in 15mn some have 4, some 6 some 8...

@JR1 ok. I had report it just now. I try to get my mayor back then. Thankz a lot.

If someone was to use GPS spoofing with the official 4 sq app, do you think 4sq would flag their account?

Q. How do I report abuse or harassment?
A. If you encounter inappropriate tips, shouts, or venues, or if you are being harassed by another user, send us an email at privacy@foursquare.com. Only emails on this subject will be replied to.

Here's what we'll require when you file a report:

-Your foursquare username or user ID
-A detailed description of your issue
-A link to the foursquare tip(s), venue(s), or user(s) you’re reporting.

Our support team will get back to you within 3 business days. In the meantime, do not engage with or communicate with the user via foursquare tips, venues, or shouts. We also recommend you remove this user as your foursquare friend by going to foursquare.com/manage/friends, mousing over his/her name, and clicking the “x” so he/she won’t be able to see where you’re checking in.

Q: How to checkin "Off The Grid"
A: When you checkin using 4sqr mobile there is a pull down tab that is set to say "show this checkin to friends" just change it to "hide my location" and that will check you in "off teh grid.
-Or-
When using any of the 4sqr smartphone apps just set it to not show the checkin to your friends. I know on the blackberry it's a check box on the checkin screen. Not sure where it is on the other apps. But it is the same concept as when using 4sqr mobile.

In Settings, I unchecked "Include me in the public list of people who are currently checked in at a venue". You can still check in on the grid and share it with your friends, but other users won't see you there. I've worked too hard for 264 badges to let someone like that take it from me. Another good thing is to resist the urge to fight back with words when someone says something bad to or about you on 4sq. Best to run to mommy and tell instead of getting in a spat. Also, don't take candy from strangers, and don't make them your "friends" on 4sq. :)

In honor of my acct getting flagged for using 4sqr mobile I asked 4sqr this ?

Q: I just got an email from 4sqr about a checkin that stated " Our system detected that some of your check-ins do not follow our guidelines". Just to clerify from what I have read on your information page stated that "- We currently do not flag accounts or check-ins that use the mobile web, as those check-ins are not included in our venue stats, venue specials, and social game elements. (This means that they do not negatively impact other members of the foursquare community.)". So why did I recieve an email stating that my acct could be flagged? Would like some clerification on that.

A: To answer your question, no user is exempt from our House Rules. It doesn't matter how you check-in, if you're going to be using our app, then we'd like you to follow our guidelines.

I know a journalist that might be able to get an answer. I'll have him contact their PR firm and ask for a direct answer.

Sorry, the site threw an errror, but save the message.

I only can level-up 17 badges within 24 hours using mobile web. After unlocked, I deleted my check-in history for venue #1 up to #4 & keep my check-in for venue #5 where the badge unlocked. When I tried to unlock another badge to level-up, I got points for 9 new venues but the badge not unlocked. Delete my history check-in for these 9 new venues & try another check-in to level-up another badge, but same thing happened. So now in my check-in history there are 17 venues which unlocked 17 level-up badges (far below the check-in limit at 30 venues within 24 hours). Does it mean 4sq limited the badge unlocked for 17 badges within 24 hours?
