We don't allow the use of any automation tools on twiends. If you're using any kind of tool to automatically reload your browser window then you're doing something wrong. We actively monitor for accounts that make an unusually high number of page requests to twiends. If we suspect something is wrong then we place the account under monitoring.
If you are just looking around then you've got nothing to worry about. Please carry on! We don't suspend accounts that are using twiends normally.
Just wait a few seconds and try again. You'll be able to use twiends again in a very short moment.
