Then I’d say that’d be a great 3rd party plugin for Lemmy (which they just enabled support for btw). I don’t think that should be a core lemmy feature, to be dependent on a list of query parameters that need to be kept up to date, but it would be a perfect use case for a plugin, which could call out to a database/script/file of known trackers and their domains, and throw up a warning like you’re saying.

Not trying to demoralize you, actually the exact opposite, this would be a great project for you if you already have a list! If you built a plugin that could do that for Lemmy I would be one of the first instances to install it!
