Man, you didn't even have to add the second part.
"How would you feel if your comic blew up very quickly?" Anxious.
Because every time I've EVER watched this happen, it was always too much for the creator if they hadn't had time to build up to it. Wishing for sudden fame is a freakin monkey's paw wish all on its own -- you think you want it, but there's a very good chance that you really, really don't.
Most fame that looks sudden actually has years of slow build behind it -- when an artist is truly new and truly has a fandom explode out of nothing, even an enthusiastic supportive fandom can ultimately hurt them just by being too much to take all at once like that.
If I'd had the time to build up a really large fandom.... honestly, I think some bad apples kind of comes with having a huge fandom. I think that'd still be hard to deal with, because numbers that huge are always hard to deal with -- humans aren't good at understanding proportion. 1 out of 200 people says you're bad, that person can be ignored. But 100 out of 20000 people say you're bad...... that's harder to brush off, even though it's the same tiny fraction. But if I ever worked up to something huge, I guess gotta accept that no fandom stays pure forever. There's always a small percentage of horrible people, and the horrible people are always loudest. It's a thought that's a little scary, but all I can do if that somehow happens is continue to be myself as long as I can!
