I used to use the newsgroups to advertise for my own sites back in the day. Worked very well back then.
But the newsgroups are dead now. The only folks trolling those areas are hackers and spammers.
So one reason it's not a good idea to use the newsgroups nowadays is because of all the attention your giving your sites to the wrong type of pple. If you want consistant and relentless hack attempts at your servers for months to come, go ahead and advertise on newsgroups. It's a waste of time and energy now. No one beneficial to paysites uses them anymore.
