Only allow three level 0 comments on a post per user (WIP)
Users should only be able to comment three times on level 0 on somebody else's post. This is a spam vulnerability. Any user who has multiple comments is freely able to comment into the nested replies of their initial comment.
When a user attempts to comment on level 0 for a fourth time, prompt a toaster error that reads:
"Please use nested replies for any additional comments on this post"
