Hello, So I have recently started youtube advertisement for my CPA campaigns, so far i got some results out of it. The thing I wanted to find out is, if it is legal to use mass adding/subscriptions tools in youtube? I mean im not spamming them with messages or spamming comments, i just add them as friends and subscribe to their channels. Any ideas? I personally think it is completely legal to do that, but I just want to hear second opinion. PS. Im running three Tube Toolbox campaigns from my pc, do i need proxy or im ok without it? Thanks.
