I'm pretty much since the beginning on Matrix. I have never experienced any questionable content. Large chats (thousands of users) have some spam problems, but the spammers banned quickly and the posts are being removed.

What am I doing right?

Not joining the rooms Element suggests on its own client? Element will show you a list of suggested, popular rooms to join, and a fuckton of these are overrun by spammers and worse. If Matrix has basically zero ability to curate these rooms outside of "here's what's got the most members", then it absolutely should not in any capacity be recommending them, let alone as a way to get started for new users. It's fucking ridiculous, and before you say "Well why should they be expected to curate the rooms they suggest?", imagine the fucking disaster Discord would have on its hands if it started recommending servers, and several of its top 100 claimed to be related to popular FOSS applications but were actually completely unmoderated and filled with CSAM and Bitcoin scams.

just this week I've had multiple random matrix accounts start a chat with me to post an Imgur link with some Hitler bs. I assume they just chose random members of one or more fediverse related public matrix rooms to send that to. they probably just do this with random public rooms and the fediverse relation didn't matter.
