Selling forum accounts is allowed. Selling signatures is allowed
True. And also true.
I don't understand why members disapprove of this.
However, both of those things lead to one common problem: spam in the forum. Lots and lots of spam. If you have multiple accounts, why would you bother posting quality content when you can just spew and generate as many pennies as you can? If signature campaigns are disabled, do you think account sales would be as high as they are right now? Probably not. (They might still be used for future scamming purposes, but that's probably it)
Explain to me why buying an account would be a
good thing. There's only two reasons I can think of for why someone would want to purchase an account: to either scam or spam.
