I installed NoScript in FireFox/Seamonkey (Seamonkey is the continuation of the Mozilla suite.) I allowed www.sailnet.com
but left all the other scripts denied. The chatroom is also gone but it could come back when clicking allow on one of the 5+ domains which were linked from sailnet.com but have blocked scripts.
The ads for the dating site with foreign women is gone too.
You can set it to allow all and then block scripts on the 10 or 20 referred domains (it includes second hops from here), or deny all and allow scripts as you please. It's your choice.
I usually allow all and then deny as I see fit. I got so annoyed with the web 2 interface on Google where it keeps completing what I type in and slows me way down that I blocked scripts on google.com. The link to the cached page in search results has also returned.
Note that envolve.com is the one that loads the chat room.
