To avoid getting account hopped this has worked for me so far, the Account Hopper will send you an ally request accept it. then as he is backing out of the lobby or game you can either delete it as soon as possible or not so sure about his but I was told by Hacker that they cant Hop an allies Profile so leave it there for a short period of time then delete it later.   if you Have HB  and gecko there is a code that can be put to the SD card and is supposed to block them from Hopping you.  not 100% but accepting their request has worked for me.  The ^1[DHM] DOES NOT WORK anymore....
