You are a very important part of spreading great information.... I would say the best information out there... But giving up is the wrong thing to do and does not give a great example to others. You have intelligent followers who can think for themselves. If you mention Steem each time in your videos at the end and the advantages this platform has you will see that you will get more and more followers here.

Besides, your videos can only be discussed here freely as you can say that deleting comments is not in your hand here... So turn off as always comments on YT and elsewhere and refer to Steemit for commenting (also post your YT-videos here, so that they can be discussed and rewarded here).

My two cents. :)
