Twisp is a Twitter Spam fighting Powershell script that searches through your followers and provides insight into the most likely spam candidates. Twisp first gathers a list of all your twitter friends and compares it to a list of people who follow you. Anyone who follows you (who you aren’t friends with) goes into a list of potential spammers.

This list is further refined by comparing:

• How many friends do the potential spammers have to how young the account is.

(If the account is only a few days old, but they already have friended 500 people, they’re probably spammers)

• The ratio of their friends to their followers and the total number of their friends

(If they are only followed by a quarter (or less) of the number they friended, they’re probably spammers)

• Their bio to keywords such as “media expert” and “SEO”
• If they don’t have a profile picture

The index of spamitude is calculated, then displayed next to the potential spammer’s name in a simple GUI. Use the checkboxes to select multiple users, then either click Block to simply block the users, or Report which will first send a Direct Message to @spam with the spammers usernames (thereby reporting the users) before blocking the users.
