Oh users who leave pages open are also getting timed out by cloudflare but I assume that change was intentional.
In that situation users just hard refresh the page and go through cloudflare a second time

But this can be annoying because it often takes longer to write a post than the time-out. So I had to copy this post, refresh the page, paste it and post it really quickly to get it through.

A spammer would not be typing manually so this is just nuisance for users, though of course I understand if it's all in the greater good.

Thank you for your efforts managing the site and curb stomping pedoposters and spambots

Thanks for the report.
I've not experienced similar issue, but talked to users who just might.

And we need pages for the ban list. Seems like 1000 each is great.
