Spammers are getting smarter and there are a couple reasons why they exist and I'll run through them here so people understand.

1. The casual spammer is a person who just does it for their own enjoyment to waste your time and frustrate forum moderators and admins.
2. Professional spammers are people who are employed by websites to post messages and links back to their employee site to build traffic so they can sell advertising, this is the most common form of spamming.
3. Criminal spammer employ tools or programs to automatically send spam messages on forums or to emails so they entice you to click on links that will get personal information from you e.g. bank details, addresses or contact numbers etc.

How can you tell a spammer from a regular person?

Spammers tend to sign up and then post the same or similar message in lots of places on the forum at the same time.
They ask lots of questions and provide a link to their website(s). This makes you want to discuss and answer their posts, which in turn increases the likelihood of someone clicking on their link so they make money from it.
Their posts tend to be off topic or in the wrong place.
The spammers English is generally poor.

Moderators and admins have some unique tools on the forums to identify a spammer, but your help in looking out for some of these guys will help the forum be free of these pests. You can click on the 'Report Post' and it sends an email alert to the mods and admin and we can hop on and ban them.
