Taggers

You know those graffiti taggers that tag our trains, buses and everything else? Why on earth do they do it? What they do is so pointless, it's not art. Yes, I admit, there are some who create really good graffiti and it's visually pleasing but can't they just do it on some great wall where they're allowed to graffiti? Yeah I know they do have their own wall already to graffiti but obviously there are not enough.
I just hate it when I see those really lame taggers, you know the ones that just look some randoms signature? Your tag sucks so stop tagging every bloody thing you see!!!!
Seriously, one day, I hope I can see our communities plague free of these stupid tags...
