You found that this person dont deserve the merit points you gave to him, because of this post other members gave him some points, but you can do nothing to cancel your act!!! This is why I believe the merit system should be reviewed.
Well the award and the thread has generated some great discussions, and it has enabled a few others to earn some merits. I'll justify my award by looking at the good that came from my generosity.
ps. Talk Merit says - I hope the bugger gets banned as a result.
Shouldn't you edit your first post though? I was also ready to give him a merit but then I noticed the answers bellow your first post... most people probably read the first post and maybe the last page though!
And hey, one more good that came out of it: I learnt the meaning of the word "plagiarist"! Even though I'm not a native English speaker, it's very rare for me to encounter English words I didn't know. Thanks for that!
