I want it that way

There are 4 main types of Spam, IMO.

Smilie Spam: Excessive and repeative use of smilies.

Multiple Posts of the Same thing: Posting something like "AWTA." on it's own and nothing else.

Advertising Spam: Obviously just bots.

Posting Off Topic: Something that doesn't add anything to the conversation, and only being posted to up your post count.

In future, don't talk about spam as it only worsens the situation. Send me a link via visitor message if you think something is spam and I will sort it out.
