people of a certain age might remember that episode of Grange Hill where Pogo got the cane for running a "homework service" i.e doing school work that other kids could pass of as their own and charging them money for it. 

the headmistress described it as a "thoroughly nasty business".

you may not ply your trade in the boys toilets or behind the cycle sheds, and you may demand fifty quid a time rather than a bag of sweets from the tuck shop, but if you make your living writing university style essays and selling them to students to pass off as their own, then you're still engaged in a thoroughly nasty business. 

so if you work for one of these disgusting companies can you please stop using the comments section of my blog to swindle gullible and dishonest people out of their cash. 

it really isn't any more convincing if you say "Gee [Andrew] I am a big fan of [Doctor Who] although I have never watched it and I really like what you say about it" before the "come and look at my website" part. 

i can't call in the deputy head to whack across the knuckles but I can systematically delete all your nasty little messages.
