I had the same experience. Writing something like lemmynsfw_dot_com so that it isn't recognized as an URL (still) works.
!asklemmynsfw
Think /r/AskLemmy but way more NSFW.
Treat this community like a cross between /c/AskLemmy, /c/Sex, and /c/Fetishes.
RULES:
All posts must be in the form of a question and be largely NSFW.
Only text posts are allowed. Links can be posted if they are very relevant.
POST GUIDELINES:
Try to avoid questions that can simply be googled or have yes/no answers.
Search before you post. Your question may have been asked before.
If you ask medical/physical questions don't always trust the comments here.
COMMENT GUIDELINES:
Avoid low-effort comments. Lone images, memes, jokes etc.
Treat all questions as if they're real, no matter how ridiculous.
Follow reddiquette with all reponses to avoid downvotes & removal.
