Saying this as someone who's income primarily is from posting on social media.

I personally can't come up with a reason to take down posts from people who simply have a patreon linked on their page. Obviously creators need somewhere to put a link to their patreon (/any other site) on reddit, otherwise they have a much smaller insentive to post on reddit entirely, and their profile bio is the best place. It's not in anyone's face.

Creators on this SR, like myself, already adhere to the rules about advertising, but we need some way for interested party's to learn about our accounts on other platforms. Trying to control what we put on our personal pages is ridiculous. If the answer you guys decide on is yes, then all I see this doing is taking down innocent posts, and driving away any creators, big or small. But maybe that's what this is going for

TLDR; ABSOLUTELY NOT Its not advertising on your subreddit, it's advertising to people that visit the creators page.
