Hey guys, I just wanted yo know if there is any plugin or program that lets us know if we have been banned by any of our contacts.

Thanks in advance!

You're asking for a block checker. Fact is, there are no good ones out there. If I check the box "Only contacts in my allowed list can see my status and send me messages" - which I have - then everyone else will see me as offline. This includes block checkers. So even if I were online, block checkers would always detect me as being offline.

A bit more detailed: block checkers allow you to enter the email address of your contacts, and if it shows online there, while they're offline in your list, you've been blocked.

Note: these checkers are very unreliable, as I said before: with my settings, even if I were online, block checkers would always detect me as being offline.
