I am whitelisted by virtue of my copper membership. My understanding is my whitelisting gives me a maximum of one action every 4 seconds, which is not frequent enough.

I have seen that table. I am not trying to send mass PMs.

I was using multiple tabs to report posts. I had identified a spam bot that used many accounts to make substantially similar posts and needed to report many posts at once. Creating a bot to report the posts would have resulted in the spam bot being able to make spam posts faster than I could report posts (in theory).
