Recommending obviously fake accounts as "people I may know" repeatedly

Something odd has been going on with my "people you may know" list recently. Many of those profiles are newer, have a very small number of friends (typically single digits, none mutual), and are obviously fake (like an AI profile photo). I'll either remove the suggestion or block the account, and a couple days later there is a different one with the same pattern. I know that no one REALLY knows how FB puts together its "people you may know" recommendations beyond mutual friends and being geotagged at the same place, but I'm really curious what might be going on with this. Is it possible it is someone I have blocked making a fake account to look me up, so it's showing up to me as someone I may know?
