Nsfw or nah? (Patreon)

Hi folks! My new comic Goldenfall is gonna be nsfw at some points, and I was wondering what the best way to filter that is - Patreon doesn't have a way to flag certain posts as nsfw for some reason, and as far as I can tell there's no way to tag something nsfw and have ppl who don't want to see it be able to filter that tag to not show it specifically. Would prob have to put a 18+ warning on my page.

The only ways I can think to do this is to either make a tier specifically for it (but then all the above tiers would still be able to see it), or to just post it and hope the people who don't want to see it just ignore it? OR I guess I could post it to it's own website with an 18+ warning before entering, and just post the censored version on here? 

What do y'all think? (Sorry that was super long)
