Most spammers on Twitter have to repeatedly create accounts after they get suspended. Since the accounts are always new they have relatively few followers. For this reason, Twitter’s algorithms that detect spam are more sensitive to accounts with fewer followers.
Recently, a group organized under the tag #TGDN has been connected with coordinated spam-blocking. Accounts with few followers are particularly susceptible to their attacks and likely to be suspended.
To protect yourself, it is important to have over 3000 followers. The quickest way to make this happen is through a mutual follow list, where all members agree to follow one another.
@UniteBlue launched that list yesterday night, and it is about to be maxed out. So we will start a second. Then a third…and forward until we have a network so large no progressive is suspended again.
