I'd do it. I'd remove this sig. I have two of the most reputed Indians Indians who have (sort of) vouched for me NOT being a scammer.
Henchman has served his purpose. He has been humiliated. I am now not a scammer
But changing my sig wont change me, I might find some new prick picking on me to be annoying enough so I'd put his name down there.
But for now yes I'd change the sig
Dude come on.. Move on.. Learn to ignore stuff.! You should come and live in USA for a couple of months.! You will be astonished as to how bad is a average person's (videshi) ability to interpret and to be diplomatic and be unbiased.
Thumb Rules..
1) Provide all the evidence and whatever you have to say in a diplomatic way.
2) Trust no one... Keep a paper trial for whatever dealing you do. (I learnt this the hard way from my boss when i was working in India.. He used to screw me for his mistakes)
3) Ignore and move on.! You have a lot of stuff under your belt. Don't waste time fighting or brooding over a issue.!
my 2 cents.!
