I guess some people don't appreciate the help. I understand where you're coming from as I do Graphic Design, Website Development & Photography. Tho I don't offer these services on my YouTube channel (advertising it) nor do I post comments on videos asking if people want some work done for free. I do however advertise my website that has my portfolio & personal blog along with other things on it on my videos like in the description, etc now if people go to that on their own free will and then I get leads but other then that I don't do the whole comment on other videos asking if they want help with graphics etc. The way your asking doesn't seem to be in a rude way but I guess people these days take offense to everything.
