I used to boost my videos using vagex. That was around 1 and a half year ago. I havent used Vagex or any other exchange service for quite some time now. I have heard that Vagex is pretty much .... useless....now. For those who use shareyoutubevideos and/or megayoutubeviews or any other exchange service(that's what there called right?) , can you plz review them for me. How good are they for views , likes and subs? can they get your video frozen or deleted? Should I worry about my ideas and niche getting viewed by competitors?
