You got caught by the bot protection. It happens. Get your IP and DM AOU begging to be unbanned. Eventually it will unban you anyway but asking nicely helps.
begging
lol wat, not really.
Shit happens. As we talked about, Poal is under an ongoing/permanent attack (botnets), but if a legit Poalr gets blocked, they probably triggered the anti-flood algorithm by browsing too fast. Unfortunately, that's the only way to keep the website going.
The blocking lasts for one hour, and it increments exponentially.
Like I said before, if that's really an issue, I'm willing to Whitelist those who of you who get blocked.
I believe the reason for legit accounts is certainly related to browsers that keep tabs in a session, and reload them all at the same time when it crashes or gets restarted.
