Bots or whatever this garbage is

I swear to fucking god I am gonna lose my shit if I am gonna see "Hey! How are you doing?" "Good. Wbu?" "I am a graphic AI shit designer that wants 150$ for 5$ ChatGPT image"

I am gonna lose my shit. It's so annoying as a small streamer since I am happy for anyone entering my chat but then they are coming at me with this bs and I am going to lose my shit if I see one more message like this.

What do I do? Do I make them follow me for minutes-hours to start chatting? I have 15 followers and I don't wanna discourage anyone from my stream just because of this garbage.

Or do I just straight up block them?
