I think I've already tried to explain this, but let me do it once again.
If I may, just because you can keep up with one account using 100 alts doesn't mean everyone else can. Alts exist for the sake of transparency. I don't RP as Sam when using my Gin account, or at least not if Gin isn't present. If he is, I label who's talking like:
Hi
Sam: Hi
With the unlabled sentances being who the account is (Gin) and the labelled ones, obviously, being the person who isn't named by the account. Alts exist for the sake of clarity. Not many people enjoy having to scry through a wall of text for all the people who are supposed to be a part of one persons actions, especially since you tend to use like three or more characters with a single account at times.
And if that's too hard for you, Light, Just use one character per RP instead of five. You don't need to have a gang. You can go solo. That would solve your problem with alts as well.
