Wasn't sure where to put this, sorry if it's in the wrong place.
Whenever I buy a neopets account I get frozen. I now hear you're meant to use a proxy for a little while, does anyone know for how long? Thanks. Any other tips would be appreciated.
Ideally, several months. You're essentially securing an account; as with items, it can take a very long time.
You can disable the proxy after logging in, though -- just be sure to enable it again before you log out.
Edit: by any chance do you instantly begin posting on the boards after purchasing an account? That's another thing you should avoid. Update the cache first, so that fewer flags are raised.
