We have a new kind of spam. Took me 2 weeks to figure it out They post under New Member Introductions and it's not obvious, like the movie spammers. They don't mention chickens, but talk about this site in very complimentary terms, the work they do and most mention a company they own/work for (spam for?). They are usually very polite say things like "like this website; very friendly people" and use bad grammar. And the posts are signed very formally. They also mention their name/company name more than once.
I asked the mods to have a look and they confirmed that it is spammers. So if you spot something along those lines, report it.
