If it's any consolation, this probably ISN'T a FTM conspiracy ad, it's most likely targeted ads being weird and inaccurate. It's "Hanlon's Razor" - a principle or rule of thumb that states, "never attribute to malice that which is adequately explained by stupidity".

I'm a feminine guy in my mid 20s. I have had accounts both with my real info (Real birthdate + sex) and fake ones. Until recently the Google account assigned to my android phone had me listed as a 60 year old woman, or something like that.

And regardless of the info, the ads are never at all accurate. I often get ads very obviously targeted at straight females, dating apps and romance novels for example. On Reddit I usually get ads centered around protein shakes, fitness etc when I've never been into that. And my YouTube mobile ads are the wackiest of them all, I see everything from advertisements for Barbie dolls to "best blue cheese recipes" to 18+ erotic gay manga ads to ads about fishing. I am not into any of these things nor watch videos about them, which is weird.

I think ads are more likely based on browsing history than your data. Which would explain why my ads are all jumbled, since I have morbid curiosity about most things and I explore around a lot. Therefore if you spend a lot of time on discussions about trans and transition (pro OR anti) you're more likely to get ads about it. I know that before my tumblr got banned and I had more "LGBTQ+" in my browsing history I was getting "woke" ads too.
