That is an odd warning...did you neomail the person or post on the board that they were using sexual, I mean did you type that word? That may have set a filter off, causing an auto-warning (yeah, I know, there's no auto anything

).
If you simply clicked report this message and typed in there that the person was trying to say something sexual in symbols, then it doesn't make any sense.
Of course, there've been alot of weird warnings lately. People are posting them on the boards (which is not a good idea - I've seen people get a warning for posting that they got a warning!) and what they're being warned for they have not done.
Oh on warnings, and the whole issue of certain words that are used on the site; some people saying they're fine, others saying they're not fine, some getting away with them, others not...Here's a copy and paste of a warning someone posted (not mentioning any name here):
Quote:
You have received an official warning from the Neopets Team for violating the Neopets Terms and Conditions.Profanity is not allowed anywhere on Neopets (including in NeoMail, the Battledome, on the Boards, in Shops, Guilds, trades, etc. even if it’s from a song or movie), and using spaces, internet slang or symbols to try to hide it is not fooling anyone. (Also, just because the filters dont change a word doesnt mean youre allowed to say it.) If you continue to break the rules, your account will be permanently frozen.

Note the "
just because the filters don't change a word doesnt mean youre allowed to say it"... that sure sounds like the h and d words shouldn't be posted.
