I'm a avid reader and gamer and I want to be able to post affiliate links at the end of my content. I hate spam a lot so I wouldn't put a link where I feel I didn't contribute value to the reader first. Is there a rule against affiliate links? Is there a special vetting process one has to go through? I would optimally like to re-invest in the steemit community to produce better content. Thanks in advance for your replies and opinions.
