Those are all over the place, and nothing but gimmicks, hoping to find someone gullible enough to believe it and click in. Then they go even further and assure you a "free" profile. And yeah, it's free to sign up. But that's all. You can't answer someone's PM, you can't send one, you can only view the one picture on their "avatar", so you essentially have a free profile that's absolutely useless. Unless you pay for a "Premier" account or whatever they call it.
Your surfing habits probably had nothing to do with it, they pay the website to allow them to place that banner ad there, hoping to get people to click in. I've seen them on fresh computers 1st time online, no way my browser could have had any porn cookies. (I've been a computer tech for 15 years and always have to try everything and make sure it works, especially with a fresh Windows install, including internet)
Very deceptive, bordering on dishonest, same as TV commercials for "free" profiles on dating sites and "free" scans by computer security software. Sure the scan is free, if you want the software to actually do anything, you have to pay for it.
I'm also moderator on a computer tech support forum, one of our members decided to try one of those free scans. I don't know which one, mycleanpc, pcmatic or whatever, he didn't specify. But that's exactly what he found out. The download and scan were free, once it fond some ungodly number of problems they wanted money to fix it.
Ditto for the dating sites, it's free to sign up. Nothing else is free. And they also now have your email address...bad news...that's where all those spam emails are suddenly coming from.
NOTHING is free...especially on the internet...
