We do the same thing (changing tags, titles to go incognito so ppl won't back out of the game), but this is different.  This is actually using clan titles that haven't been earned through leveling up.  I reported that it is being done, and was told it would be looked into and to report it within the game if I saw it.   The problem is, you can't really tell in a lobby if they've done it, you have to know the name of the clan and search and see if they've actually earned the title they are using.  By then the game is over and you've lost the ability to in game report.

Someone in my clan sent me, privately, a video on how to do it. (which I will not post here b/c I don't want to spread the word how to do it.)  We are all PO'd about it, because we've recruited hard to get our clan to level 13. 

FYI:  You have to actually look at the clan itself on elite by searching for their clan name because you can't tell what level a clan is on in the game.  Someone else in my clan was a member of a clan that had actually earned the yellow/black clan title.  When he left that clan and came to ours, he didn't lose the title, but he can't put any thing on it, so you know it's not a clan title if he uses it b/c there are no words on it.  The people who are gltiching it can actually use it (or any one of the clan titles) and put their motto on it.

This is so not cool.  I hope they fix this glitch because some of us are working hard to get where we are as a clan.  Taking advantages of glitches or cheats is not fair to the rest of us who are trying to level up legit.
