First of all, you may say "SBYP". But this is different. And it's a club (well sort of).
So in this club we will disguise ourselves as "____'s fan", but the blank has to be someone who gets very little appreciation for their hard work. Why? Because those who do get appreciation already have loads of fans (and ACs XD).
So you don't have to say "I will join this club". I won't even keep it down somewhere. Just talk here about people that need more likes than they have now.
