All ads are questionable, are privacy and security risk and should be blocked by default. On android I can recommend AdGuard.

Use Smaller Cards view mode and there isn't adds.....
Look for the ℹ️ button in the ad, or some form of informational button that will bring up more options without actually opening the ad.
That should give you some options to work with.
Are you speaking on posts on Lemmy that are ads? Or the ads within sync? I’m sure those questionable ones are the most profitable for the developer and they would have to drop whoever they’re using to distribute ads.
Number one thing about Lemmy is there’s no ads no tracking, etc. Blows my mind that people come over here and deal with them.
