I don't know if this is the right place to ask this. But anyway, tools like MP are great with social media, following people, seeing if they follow back, etc... An easy way to build up a base of real followers. On YouTube, I've noticed that if you have you subscriptions set to public, people will get an email when you sub to them. So I wondered if using a tool that subscribed to people who have interacted with similar channels would be a good way to gain some exposure. Has anyone tried this?
