All of these sites do shady shit. I'm so glad I'm no longer single.
I signed up for eHarmony with a unique email address dedicated to that site. After wasting 6 months, I chose to delete my account.
Lo and behold, soon spam started to show up on this account, as if the floodgates had been opened. It was a unique account that I had not used anywhere else just for this specific reason, and my hunch was justified.
I do this for every site I sign up for. I have a 'catch all' email address, so I can put [email protected] and the emails will get to my inbox. So now I know who is selling or leaking my email address. So far it's been very few, but I also don't sign up for new sites very often.
They were good 15 years ago. As with all things, it went to shit when Match.com started consolidating everything and the bean counters realized that a quality product was not as profitable.
Surprised it took this long to get litigation. So many people complaining about how crap dating sites are, but no one thought to realize the site itself was the problem and fell into the whole "looksmaxxing" grift. Some people really will do anything except admit that rich people are corrupt.

Facebook is also guilty of this.
I set up a Facebook account for a relative around 2006. The e-mail address is name_facebook@ a domain that I control.
Every six months or so, Facebook will send out almost daily e-mails for a month saying "Person x commented on your post!" or some variant. You know how I know this relative of mine didn't make a new post?
He's been dead since 2011.
