Escape Youtube spam syste

Hello guys. I searched this blog for similar threads but i they are all outdated. I have been using manual youtube spamming to advertise for about 5 months and ive been doing great, earned almost 3k. The problem started a week ago when my comments started to dissapear after an 2-3 hours. I changed ip and mac adress numerous of times but they still dissapear. Also i tried one comment with Enhanceviews from other people and their comment is flagged as spam too. Maybe youtube doesnt allow anymore last part of the video like /sdjfs9djg56, but if anyone have some ideas to share i would really appreciate it. A delay between comments would probably work but that would be slow manual. Ive been using this method without a delay at all it has been working perfect. If anyone has some suggestions please tell. Thanks !! Sorry for bad english

i think the problem is mainly you just spammed away without any intervals..

But i was doing it for 5 months without any interval and about 80 videos with one account. Everything was perfect! I forgot to say that i got a message from random guy saying "say good bye to your isp" it was a month ago.. i dont know it is related to this..
