Blacklist domains to make sure you never waste another hit on them. Be sure to sync your blacklist regularly.
If you want to be polite, you can fill out a reason, which is not only to help you remind why you
blacklisted some domain, but it's also displayed when that domain tries to signup again.
With this form you can quickly blacklist multiple domains at once.
A blank reason is stored.
This table shows you the blacklisted domains and the reason (if one was given).
It's also possible to remove a domain.
