Fantastic! Thanks for posting, right laugh 
so its ok to do this, but we used to hit up stickers with our names on and we get nicked for it…
bit like its ok for Banksy to paint a wall without any permission, someone else does it and its bang out of order.
CUNTS.
Superb!
I particularly liked…
‘Pull lever to pour gravy on sausages located in drivers compartment’
I think you’ll find it’s just as illegal for them to do this, and if they got caught they would face the same penalties as you would.
But I find it much more amusing to read their comments than your name (sorry dude, ratty is funny but not that funny :D)
As for Banksy I think again if he was caught before he became famous then he would have suffered the same.
But there is a very very difference between street art and petty vandalism so let’s not try and confuse the two
People are probably not too worried about getting ‘Banksied’ because it turns £300 worth of brick wall into 10 grands worth of art
street art is different to ‘proper’ graffiti, pure graf is illegal, its how it started and its how it should really stay.
street art is for the hoxtonite trendys that dont know much about real graf and i from a very different background normally, respect to banksy tho he done his time and he aint a bad fella;)
hes clever!
i very much doubt they would get the same penalty, you dont know BTP graf squad…
btw i never wrote Ratty, thats my forum/biking nickname, i wrote something very different, and its very unlikely im gonna divulge it:D
i no longer write, retired some time ago, but i know they would still like a word lol:D:w00t:
Lol true that it’s not the same… I think the main difference is that sticking these on is removable, proper graffiti is a lot more permanent 
I trried my hand at graffiti back in greece but after a few attempts I realised I was crap at drawing anything other than stickmen so I gave up…
