Board Thread:Support Requests - Getting Technical/@comment-4146635-20140214234220

Hi! This is very urgent. Is there a way I can hide the contribution page of a user (particularly a bot)? I want the Special:Contribution/USER NAME page of a certain user to not show their contributions. Is this possible? We're having a hunt on our wiki and with that page of the particular user, other users can cheat. Someone please help me out, thanks, and happy Valentines Day! :D
