Spam is an inevitable pitfall of online life. Especially on Twitter. If you haven't seen it already, check out @spam, an account that keeps Twitter users up to date on the latest spam issues and what to do to avoid or rectify them.
Sometimes, spammers get especially crafty, so we can never review too many times the classic marks of a Twitter spammer. Watch out for the following:
1. The "person" on the questionable account has WAY fewer followers than they're following, or no followers at all.
2. Their profile pic looks like a stock image (and usually, it's of a female).
3. The tone of their tweets is a little over the top or out of context ("Get 10,000 followers in a week!" or "Did you hear what this person is saying about you?").
4. The account hasn't tweeted anything.
5. You've received a direct message or mention from someone you know, but they're acting out of character, i.e., they're mentioning or direct messaging you with a link for the first time in your memory.
6. The tweet mentions you but there's no message, just a link.
7. The Twitter bio or tweets contain grammatical errors and/or decidedly racy language.
