A reminder/note to self-hosters:
Adding “random” LLMs to deal with the spam problem potentially opens a can of worms in terms of privacy and protection of personally identifiable data (PII). If you’re required to follow the GDPR or COPPA etc., the use of external LLMs might require you to enter a data protection agreement with the LLM provider to ensure your site doesn’t bleed PII to a third party. And PII start with simple things like names and email addresses.
This is just something to keep in mind.
