There's no reason for that error to happen unless the admin/player has deliberately modified their game to block the command. The plugin forces the player to execute those commands (in your case amx_asay), and that command is not in the list of commands marked as slowhacking by Valve, thus that error won't occur unless the game is modified to do so.
I've not modified my game to block commands, not even using cl_filterstuffcmd 1 except putting all files to read-only. This should not make this error happen though AFAIK. Also this error has happened to other admins/players. Pretty sure not all of them have modified their games..
Can you check, please?
