how do আপনি know when a group's been deleted?does it just not প্রদর্শনী up when আপনি research it???? O_O

Depends if the club as been properly keyworded অথবা not. If the club hasn't been keyworded then it won't প্রদর্শনী up when আপনি খুঁজুন anyway.

But if আপনি could previously find it দ্বারা searching and then all of a sudden আপনি can't anymore, then it will have been deleted.

আপনি should check your সংগঠন too, just to make sure.
