Welcome to the community. Would you mind telling me more about yourself / your channel for example what type of content you produce, when this is uploaded, how you found Freedom, or what your long term goals are?
Also as many people have said above I would never recommend you do sub4sub, not only is this bad for your channel but it is also against Freedom's and YouTube's terms of service and can actually get your channel terminated. If I could ask you to edit your original post to remove mention of this I would be greatly appreciative, otherwise I may have to give you a verbal (official) warning about this. In addition if you get a spare minute can I just ask that you read the forum rules please
