If you're sharing adult fan art of 'Red Dead
redemption 2', the easiest way to stay safe is to be explicit about it before anyone clicks. I tend to treat tagging like a courteous handshake — clear, direct, and a little formal so there are no surprises. On every platform I use I put at least three things up front: an age marker (like '18+'), a content marker ('NSFW' or 'Explicit'), and a short content warning ('sexual content', 'graphic violence', etc.). When I tag characters I include the game title 'Red Dead Redemption 2' and then a more general tag like 'RDR2' rather than plastering character names in the first line; some communities will automatically filter character tags differently so you want to avoid accidental exposure.
Over the years I've learned platform quirks matter a lot. Tumblr and Pixiv respond well to explicit 'R-18' or 'R18G' tags and to using the built-in mature content settings; DeviantArt and FurAffinity have maturity toggles you must check or the piece will be hidden or flagged. Reddit has subreddits with explicit rules — use post flairs and the NSFW toggle. On X or Instagram I often blur a key part of the image and put a clear 'NSFW — click to view' text so feeds don't show explicit imagery. Alt text and the first comment are great places for more specific warnings if the platform hides or truncates captions.
I also guard against legal and ethical landmines: never sexualize minors or ambiguous-age characters, and avoid real-person explicit imagery without consent. For copyrighted games like 'Red Dead Redemption 2', fan art is generally tolerated but monetization or using official assets can complicate things — I keep commercial uses separate and check each platform's IP rules. A small watermark helps protect your work but keep it unobtrusive so it doesn't cancel the content warning. Finally, be ready to moderate: if someone reports your post, respond calmly, correct tags if needed, and learn which tag phrasing reduces accidental views. I prefer being upfront and slightly overcautious — it keeps the art visible to the right audience and keeps me sleeping better at night.
