After many discussions in Announcing Wasabi Wallet 2.0 and elsewhere, I came to the conclusion that we need a community-curated summarized list of untrustworthy services that I call 'taint-proclaiming services'.

These services ignore one of Bitcoin's fundamental values of being fungible, usable and acceptable everywhere and anywhere. They each come up with their own arbitrary set of taint rules by which they allow themselves not only to deny your Bitcoins, but also to steal them from you and / or directly share your data with government agencies. Some people may not be aware of this, some may accept it for the convenience of the service in question, and others may prefer to stop using these services.

I'd like to encourage everyone who had such an experience or a reliable news article about something like this happening, to share it and I'll add it to the list.
For now, a few that I could find relatively quickly or remembered by memory:


I remember there are many more such cases, but can't find web articles about them right now, so I'd appreciate any additions.
