I’ve just noticed that Envato do not allow do follow links on your profile for exclusive authors.
I don’t personally have any links on my profile page but i was thinking of it, that is why i checked.
I think that a link to your business, personal website should be allowed, this will help in SEO because of how big Envato are, which in-turn helps in sales.
Something similar to the social buttons, it does not need to be text, just a do follow icon to your website.
Just a thought, but in terms of generating more sales, this would help lots.
