A "spam team" is a pair of accounts created to spam Fluther. The spamming is carried out in two parts. First, one account asks a question about a product, business, or problem. Then, a different account answers the question with a spammy answer.
Signs of a spam team:
The question is obviously about a specific product or company, and it is written by a user with very few lurve points. The question is typically written in bad English, but not always.
The answer is obviously spammy and written by another user with few lurve points. It typically includes links and sometimes pricing information. The answer also does not seem to be talking to the OP, but rather the reader.
Both users share the same IP address (only viewable to mods). This is often a criterion for immediate banning of both accounts.
Spam teams are often readily detectable, although they are harder to clean up.
