Hm, well... what kept me from Patreon is that first, you do commit to do things regularly and second, you might bind yourself to a userbase and do stuff they want to see (at least those are two points I see done often, I don't know if it is obligatory or just the way people do it). And you have to get people there, first. I wasn't as far as all the tax-stuff then, I so-to-say stopped before that ^^
They have an option that people can support or pay by creation so you aren't obligated to push stuff out on a schedule. Yeah, I got sketched out on the personal information where is it being held? Is it secure? How secure? How has my information? Are you selling it? I don't want this to be a FB error...
I'm not sure if they display other terms to you - but due to the new (one year old) regulations in the EU, they should have to tell you all that . Maybe they do tell you what applies to you. You could look up their Terms of Service - I think it should be in there. Not all (like: where exactly and how secure), but much of it. Or so I hope.
How were you able to get patreon to work if you don't mind me asking? I went through and the only reason I didn't publish a page was because I wasn't sure what I had to offer, since I offer advice and other things free anyway.
It's been a bit trial and error but had a few ideas. For example, I worked on an animation pilot and video game idea that didn't come off, but it did mean we have some stuff that we could give as bonuses.
For me personally I think it helps to have items that are only available via the Patreon. For example, I'll do a video on a Monday on Youtube for everyone, and then on Friday do a video for the Patreon backers.
In terms of promotion, it is that fine line of pushing it without being too spammy, which is the case for a lot of things I work on (I do freelance writing/social media promotion as bill paying work). One way we did on here was post the first in a series of short stories, with the rest available on the $1 tier.
