Couldn't there be some alternative like having VPNs provide a standardized API for websites to report bots from using anonymized data take from the HTTP requests? Then the VPN can block the user after reviewing the usage data they have.
That would require the VPN service to keep track of users' usage and be able to match traffic to user, which most (or most of the big ones at least) very specifically, very on purpose, explicitly say they don't do, which would be really bad for them if it turned out to be false.
I'm guessing you're not logged in. The landing page works, but the members area, where the full ratings are, will show the above screen when I'm on VPN.
You might be using an endpoint that people have used for attacks recently. I think all of the website protection tools have some sort of temporary IP blocking mechanism.
Dunno about op, but for me: various self-hosted interfaces, info for projects in-progress (easily 5-10/project), a few different forums I frequent, interesting stuff I don't have time for now but will return to when I do.
Bookmarks get lost/forgotten as I don't make a point to view them to remember them. Open tabs remind me of their contents every time I switch tabs so I'm much morr likely to return to them. I'm also lazy and don't want to re-open the same sites I frequent nearly daily.
Currently only have 21 open, but that's been much larger.
