Money, RB is making soooo much $$ on you...
Did you ever look in your browser and wonder what all those RB/Lycos cookies do? Especially the ones called "Lubid" and "Lubid2"....
They track your azz to every place you go on the 'net, then report back whenever you visit Google, Yahoo, Lycos, or MSN.
If you went to a Chinese dating website for example, when you returned to RB you would see pretty ads for Chinese food, travel to Asia, and discount chopsticks.
That's all thanks to their partnership with AKAMAI. There is huge money in ad serving. I always clean out my cookies after I vist RB, lately I've been using a special "sanitized" browser just for them. And all cookies are destroyed when I quit the program.
