Bot authors are lazy and won't until they have to.. once you do, you can then pretend they aren't bots and include them in the engagement numbers you feed prospective shareholders.
Agreed. From my past experiences though, a very good chunk of them will give up once there is a resistance. Basically, you want your bot protection to just be a little better than your competitor. Then the bot author will target them instead, because of the path of least resistance.
