Hello, I just made a new youtube channel and I want a few subscribers to make the channel look legit. I've been using Addmefast since last year but now when I try to add the Youtube channel ID on addmefast, it gives me an error "Please enter valid youtube channel username". I tried creating another channel but it still doesn't go away. Their support centre isn't replying. Does any of you have a solution to this? OR can anyone suggest me a site similiar to addmefast which supports imacros?
