I'd be horribly offended. Shugo Chara isn't even very good, CCS is one of the best anime of all time (IMO it is the best). Also, even if they did confuse the avatars they could just look up at the name, or better yet look at the content of the post and say "oh, this definitely isn't Pachy speaking."
Wait a few years, I'm sure there'll be Gen3 remakes.
