How do you feel about cross promotion? (Patreon)

Turns out promoting your adult game is much harder than I thought. You can't pay for ads and a lot of social media likes to suppress views. I reached out to a fellow developer for advice and they had this to say:

"Try cross-promotion. The idea is that you will make a post on your Patreon about someone else's game and they, in return, will make a post about your game."

I like the idea, but I'd love to hear you guys' opinion on it first. Is this something you'd be interested in? I would only highlight games that I think are legit worth looking at and only once (maybe twice) a month.
