In the recent months, there have been several reports of domain name scam from someone called "Jon Hegglund". In summary, they will ask you for the domain price and thereafter ask the domain name to be appraised by a domain name appraisal service of their choice...
Ofcourse, the domain name appraisal team belongs to the same person, and you will be paying him to appraise the name he is going to buy. And ofcourse, he won't buy your expensive domain name because he just want you to pay him money and not the other way round.
See attached for part of the email. As an Anti-Scam expert myself, I did a research before going any further. There are other links on this same issue:
Warning about Operaen at Namepros.com
Note that this is a link to a forum, so we are not sure when the listing would be available. I have attached my own email thread below. One thing smart about the author is that he made a check on the background of the source, e.g. IP address, host, etc. Although not conclusive, it may be used as a hint to investigate further. There are others, just type "operaen scam" using google search.
This email is published here for information only. Note that we did not proceed to quote our price. Instead, I conducted a research and found the background before stopping the transaction.
Btw, if I reply the email below with a price, they will definitely ask for the domain name to be appraised so that "they can be assured of a good investment price and they can sell the domain name at a profit later". It makes sense, but they will not agree to let the domain name be appraised by the older (and proven) domain appraisal sites (e.g. Sedo), but they will insist that you visit their appraisal team and Pay for the Appraisal. What's next? Nothing... thanks for the business and bye bye. Your domain name will not be sold.
