Just for general info, in the far east they are referred to as Trade Operators. One young lady joined a forum I moderate. And spent a lot of time going through the members list. Copying the sales pitch and emailing the members from the forum in house system!
Banned her and the ISP from the forum, I googled the user name and she used it in her off hours as well on some forums that her and her friends hung out on. Using the google translator She was talking about her new job. Were she was contacting people through forums she joined for business opportunities. In her country.
I guess your perspective, and putting rice in the bowl is everything, Whether it is spam or an opportunities.
There are more people that are doing that, joining forums and sending spam or just posting web sites. To keep their jobs in the US. We have had a couple of them doing that. I emailed the company, the owner contacted me and said yes he had them doing that to keep them busy till work came in. And he didn't see it any different than send out snail mail fliers. I have seen a real person join a forum and after they figure the forum admins go home on Friday. They turned a bot video file poster loose and by Monday morning there was close to 1,200 porno video clips on the forum. Some with auto start, all with a file number for easy ordering

Here is an interesting site on stopping forum spam. The amount of spammers they catch overnight is amazing.
http://www.stopforumspam.com/I was also informed that their is spammer web sites, that when one finds an easy forum they post it and it is flooded with spammers till the admin figures out something new to keep them at bay!
