Anyone else getting friend requests from people with near-porn as their profile pics?

I've gotten four friend requests this week from profiles that were all created in 2014, with young women in various states of undress / come hither type poses and looks and so forth. I approved one so that people can see what I'm talking about.

Anyone know what's up with this? Some online porn spammer created accounts seven years ago and then waited like the cicadas to strike in 2021?
