Is there no way to block users?
I have someone who's unfortunately obsessed and it doesn't seem to be a way to block users. Please make this an option?
If someone actually harasses you, you can report them.
If you are getting a lot of constructive criticism it might be because people would really like to use your stuff but wish they were more accessible. I'd suggest that you either ignore them and do your own thing or try to change things up.
After all, we are alltrying to make the best stuff we can and we are far from having one best way of doing things.
