Bot or not. It's still both stupid and wrong. The smart thing to do is to make a dedicated page, website or platform where they advertise their skills or whatever they want to share or offer.
For example, I, for one, am a content creator. (Gaming & Music). But I don't go around pasting in the same msg in which I do YT and have a discord sv and everyone should join because I want peeps to join it or want to collab with anyone. I'm not that desperate because I know opportunities will rise in time. 🙂
You might not be a bot, however, anyone who post this sort of stuff with links are sus. Word of advice, don't do this. As in, randomly posting stuff. You'll just be seen as a potential scammer or some sort.
