From 1997-1998, Harry Potter was marked Undesirable No. 1, ostensibly for involvement in the murder of Albus Dumbledore. This made him the most sought-after wizard by the government. The reward for the capture of him and his wand reached 200,000 Galleons in April of 1998.
In a broadcast of Potterwatch, Fred and George Weasley quipped "Well, that wouldn't be us then, would it? I mean, we've both had loads of girlfriends," and warned those that they truly considered to be Undesirable, such as Dolores Umbridge and Draco Malfoy, "Your time, will come."
