I agree you should join now, give them time to get used to all of you.
It would look suspicious to do that all of sudden...
I even say more, since its a BBW group, tell you all have an history with a bbw girl or woman, depending on what historic you choose for you're avi..
"Lick they're boots" but don't go to much out of the blue.
However, don't show that you all have something in common, one of you "screw up" and other might flag it... then some time later, another one puts things on it so the other flag the group and so on...
That way you'll give the group the several flags and IMVu might look into the issue.
Also if you want, you can pretend to be a very nice single, who would be interested in someone like the the one Falcon wants to screw. Play with her and try to get her give you some indecent pic and post it on the net.
