That's okay, @(you need an account to see links)! We saw your username in that post, so we took it down to keep that information private.
The error you're getting is happening because StackPath is clamping down extra hard on site activity at the moment. This is usually in response to the Neopets site receiving what they deem to be an unusual amount of traffic, and it doesn't have anything to do with yours in specific. If you've already fully closed out and re-opened Stealth, and you're still receiving this error when you attempt to log in, then you'll need to sit tight for a bit longer until StackPath mellows out.
Sorry for the inconvenience!
