Hi there, and welcome to Poal. Posting links only to the same YT channel is considered as spam and if you continue to do so (especially in default subs), your account will end up being banned. So to avoid that, I suggest you to post other domains as well. Once you will reach level 2 (40 points), you'll be able to create your own sub and submit links there, then users will subscribe if they like it. Thanks. (Moved to /s/videos)
