I've just created an account on Cross Validated, and typed up my first question.
Unfortunately, when I try to submit it, I get an You can only post once every 40 minutes error message.
I've never posted a question on Cross Validated before, and do have the association bonus. I've also not posted a question on any other site today. My IP address is probably shared with users that post more frequently, though. Some of those users may have 125+ rep and thus not be subject to the rate limit on their own account, but do end up restricting other users posting from the same IP. Thus, the limit is probably because of IP-based rate limiting.
Could we restrict IP-based rate limiting to users that haven't received the association bonus?
Users that are eligible for the association bonus are clearly not just creating accounts to circumvent rate limits, and can more easily be moderated since they can be suspended network-wide and that will also affect any new account that they create.
The current implementation likely hurts several people, such as employees at large companies or students at large universities.
