not espically
We dont' really "need" it. But do we really need each of the individual smilies? I mean I probably wont' ever use the finger one, and most users will not.
Its not much different from someone actually saying " **** You" only thing really different is the icon may not be edited by a moderator. If someone feels the need to use it against a member of the forums though it will be edited.
Basically its avaiable, and like everything else - will not be edited unless a moderator feels it needs to be edited. I believe in the TOS it says a post may be edited for any or no reason whatsoever. If a post uses it it will be a moderators decision whether to edit it or not.
