Mr Flegg specializes in online abuse, insults and death threats. He likes to barge into other people's conversations online and abruptly launch into abuse. He spits venom! His scatological language and foul temper match his picture and his name.

Be warned - block him, ban him and shun him.
Funnily enough his Facebook page goes on a lot about the perils of pesticides. Pity there isn't a pesticide that's effective enough to keep this type of pest far away and out of sight or hearing.
