 | This page in a nutshell: Sometimes, malicious editors bite on purpose, aiming to leave nothing left but a misplaced block. |
Any experienced(ish) editor is aware of the WP:BITE policy, and knows full well that biting could lead to a user leaving, or being blocked in the heat of the issue. The problem is that any experienced(ish) troll knows full well that biting could lead to a user leaving, or being blocked in the heat of the issue, effectively eating the victim whole. This, of course, creates a bigger mess for trusted users to clean up, and it's almost entirely impossible to regain a user who fell victim to om nom nomming unless you respond as this particularly egregious behavior is still ongoing.
Om nom nom noming is a particularly dangerous (for the site) form of vandalism, intentionally scaring off new users and generating a bad impression for them. The result may be them never editing again if not dealt with swiftly with a block. There is no good faith way of om nom nom noming, as it is by definition trying to scare off a new user, so any user or IP caught doing it is very clearly editing in bad faith.
