Places To Acquire traffic From

What high traffic websites is it possible to leave a bio or about about myself and in that can include my website. It need not be a clickable link, as long as peeople can copy and paste, that is fine. I can see you can do that in Youtube comments. Is there any other sites where this is possible? Is it possible with https://imgur.com? for example as I can see that this site is highly popular.

I think Reddit is an even better place than YouTube for acquiring traffic through comments. I've had a lot of success with it throughout the years.

And don't forget Facebook comments. They can be a goldmine if you're doing it right.

You can do this in quora in your profile section.
