One common faux pas on Internet forums is to post the same message twice. Users sometimes post versions of a message that are only slightly different, especially in forums where they are not allowed to edit their earlier posts. Multiple posting instead of editing prior posts can artificially inflate a user's post count. Multiple posting can be unintentional; a user's browser might display an error message even though the post has been transmitted or a user of a slow forum might become impatient and repeatedly hit the submit button. An offline editor may post the same message twice. Multiple posting can also be used as a method of trolling or spreading forum spam. A user may also send the same post to several forums, which is termed crossposting. The term derives from Usenet, where crossposting was an accepted practice but causes problems in web forums, which lack the ability to link such posts so replies in one forum are not visible to people reading the post in other forums.
