I had a situation a few months ago where i was cash strapped and needed to sell one of my best unused urls. I was fairly desperate for the money which is always a bad starting point. I placed a for sale page on the url, sent out a few non-spammy info postings on webmaster type sites and lo and behold I soon had an interested buyer, and we agreed on a fair price (a good one too, but not wildly overhigh, which would have raised my suspicions).
His english was poor, so conversation was hard going. We finally got to the part where I needed to recieve payment before sending the authorisation code for the domain transfer. His english was so poor we were just going around in circles. i couldn't be sure if this deal was legit, or a complete theft attempt. Not a clue.
Then I remembered fiverr.com - so 5 dollars later (not even 5 pounds, what a bargain) I got a professionally translated conversation going where it became immediately clear he was a scammer. "Must recieve authorisation code before sending payment, standard business practise, company procedures must be followed bla bla bla).
Best few dollars I ever spent, I was bummed at losing the sale, but to be honest it was the not knowing that was wearing me down, I was relieved to know for sure what was going on and could put it behind me.
Morale of the story, fiverr.com is your friend if you need translation services
This is not a plug, hence no hyperlink, just wanted to spread the word. Before fiverr i think it would have cost a lot more to get a translation done which would have made the fact it turned out to be a scam attempt on me sting even more!
