I’m quite happy with my instance and I haven’t experienced this myself (that I know of). I just personally would rather encounter something I don’t like than to only be able to see half a conversation.
I guess you’re right that having instance options makes this a non issue though, as we can both have what we want.
I just think a lot of people join instances like world or ml without really understanding this, which is unfortunate.
I think learning linux and the terminal is a good place to start. Once you get comfortable doing basic stuff in the terminal, it will be easy to start making bash scripts. From there, something like Python would be a good next step.
