Those become a lot easier to work with when you differentiate them from good-faith bots.

Discord does something similar, although I feel they've gone way too far with policing it.

The idea was about opening the API, and this suggestion was to argument that it makes easier for the malicious bots. So this was suggested to make the API less valuable for that purpose.

I think the only problem would be if this API was used by non-bots (perhaps some relays) and the tag loses its meaning.

I think we need to expand our vocabulary a little on this subject. A lot of people seem to think that these "bots" are just limited to "buy crypto today" type posters.

What they don't realise is that the comment they are reading right now could well have been written by a bot.

His scope covers everything you mentioned, you are the only one limiting it yourself.
