I have a few people on mine that do this, I had to comment on one of there statuses the other day to tell them to stop being a bellend 'of course you like it, it was you that wrote it you dick'
I deleted my own brother because of this, he was updating it about 7/8 times a day.
I had one 'friend' that liked 93 things on Facebook today
Those 'JK' things done my nut in as well. I had one person during the world cup last year make one up about 5 minutes after the Rob Green indecent happened, the guy has never been in a football stadium in his life and made up one like 'I can save goals lol JK I'm Rob Green' He got firmly told that he was a ballbag and that you can't save a goal you can only save a shot so if you don't know what you are on about keep quiet.
I start to wonder why some people don't like me
