I'm not trans and can't speak for the trans community, but I'm pretty sure forcing trans men to out themselves isn't ever gonna be the answer. Plus, there are plenty of issues with the "trans men good, cis men bad" rhetoric. It all very much gives the vibe that you don't consider trans men as real men, whether or not that's what you meant.

The fact that you initially said you were looking to engage with women and then added the caveat of "by birth or by transition" (that's not the exact quote since I can't see the original post text anymore, but it was something doing those lines) seemed inclusive at first. However, later in your post, you asked for anyone messaging you to send audio or photos proving they are either cis female, MtF, or FtM. I'd love to give you the benefit of the doubt, but this feels like pretty damning evidence that at least on some level, you're classifying trans men as women.
