I really need to think again about all of that. I have quite a long blacklist too. There is definitely an issue of tag abuse and I won't be able to do much on my own.
My other issue is that I support small communities like freewrite and big like fr. So it is very hard to find an equilibrium between the way I support. Maybe my service should aim at supporting only small communities later.

All in all, I am still having a lot of fun doing that and I don't think I will stop here.
Thank you for putting this awesome community together.
