I can suggest a compromise. Unless you receive a legal request, as of January 1, 2024:

1) All mixing services, ads, and links will be blocked and everything will be filtered.
2) Mixer links in signatures are allowed, but the announcement and deal agreement must be outside the forum (since links in signatures are an individual responsibility)
3) If you receive any official request to ban a mixing service or it becomes illegal, mixers will be banned from signatures.
4) If blenders become illegal in the United States, mixers ads in signatures will be banned.

This way, you will avoid any illegal liability on the forum and people will seriously start to stop advertising mixing services.
