Are there any services or bots out there that are similar to Followliker but help grow your YouTube subscriber base? I don't want to do anything aggressive like commenting and messaging. Nothing that can get flagged by other uses. I would like to do something that's more along the lines of subscribe / unsubscribe targeted users. I have competitors with large channels and there are other channels who have ripped my videos and uploaded to their channels that are 10 times longer than mine. I tried doing this with TubeAssist but after 24 hours the campaign never started so I simply requested a refund. Are there any other options? Was my experience with Tube Assist an isolated incident? My account is currently at 900 subscribers and I gain 20 or so subscribers with each upload as of right now. Any suggestions would be appreciated.
