bots on websites, on apps on forums, has anyone found a real solution to getting rid of bots? and bot accounts? if so id love to know any solutions

Living in the u.s looking for experience so I thought to do contract work through lemmy ie Tell me a project you'd like me to build, I build it. What do you gain? A software you want maybe you diddnt have time to build, what do I gain? Experience to put on my resume instead of just projects to say I was a contractor for x person (you) also I won't put your real name I'll put the software name. Or i can contribute to your open source long term. Should I make this request on forums or blogs ? Or do you guys think this might be a dead end ?
