What would you do if someone you don't want to know that you're here suddenly appeared, as a new jelly?
Imagine this scenario: one fine day, you’re browsing around. You see a question or an answer of a new jelly that you find interesting. For some reason (maybe you’re bored; you are curious of their profile; you are so impressed by the new jelly that you decide to follow them… something like that) you enter their profile. And imagine what you see: their story or avatar (or both) seem to indicate that you know that jelly outside Fluther! To make the matter worse, they are the last one you want to invite here (maybe because you talked dirt about them earlier here; you don’t want your anonymity to be destroyed… anything). There is only one lucky thing about it: they haven’t recognized you, yet.
What would you do in a situation like that?
The story will be more thrilling if you add some more “unfortunate” things into it: you have lurved that jelly; you reply to their post and thank/praise them; that jelly say something to you like “you seem to remind me of someone I know”... things like that.
