I genuinely hate defending Tumblr because they suck so much, but accounts of trans women aren't being taken down because there's a staff hit-list or something. Transmisogynists (likely gender critical hate groups based out of other websites) are mass-reporting any posts that could count as questionable under any category. Because Tumblr has had a buggy auto-moderation system since like 2018, when those reports hit a certain number, the account is automatically terminated because it's assumed that the number of people reporting means this is a serious thing.
Appeals are very likely not looked at by people anymore. Tumblr is operating with a skeleton crew. I know there are some conditions under which you can get an account back, and these usually include ones under some number of reports where there's a "forgiveness" or more so, a benefit of the doubt. You can remake with the promise not to post whatever got you banned in the first place.
Tumblr explicitly states that all their moderation is user-report based. They don't flag any content using automatic tools (as in, they removed the automatic NSFW scan filter a bit ago, but you can still have posts flagged as mature by other users) and they don't send out any moderators to look for content to ban. They don't want to be caught up in legal issues for people perceiving that they're doing something such as... Well, sending staff out to terminate the accounts of trans women.
More should be done to prevent these mass-reporting campaigns, though. Asking the Tumblr @staff to implement time limits on reporting or making it so that a post can only receive a certain amount of reports... Maybe disallowing more than a certain amount of reports within a span of time, and requiring human intervention for posts that are suddenly spammed with reports? Those are probably the most effective ways to deal with it.
Having correct information and knowing what to request from a company is vital in these situations. Accusations and chaos aren't going to get results, and this only hands victory over to the transmisogynists sending these reports when nebulous Tumblr staff are targeted and nothing is done to thwart their part in it. Tumblr should be held responsible for their lax moderation methods that allow these issues to persist.
