IMO - no one is appraising your name b/c no one sees any value in it other than Reg Fee.
It's a common trend here:
To an Experienced Appraiser - it domain has no value, nothing to appraise. Especially seeing how, after a small amount of research, there doesn't seem to be much, if any, demand for the name - thus a waste of time to appraise; looking as if the buyer didn't even do their own basic research. If you bought it on intrinsic value - then that's what it's worth.
...but if you bought it based on some perceived Market Value - then please show your research so people can make an informed decision. Not to do so only makes one look like an anxious newbie who thinks they won the lottery (but didn't) - not a professional domainer who has done their proper due diligence.
To an Inexperienced Appraiser - they just don't know the value either way, and thus do not reply.
In the end - most people are not here to do other peoples work, but to add value to the work already done, to work as a community.
Remember, there is no such thing as true Altruism - what goes around comes around in many ways, and if nothing gets sent around - nothing comes around.
...and that's my early morning 2 Cents worth.
Please Note: While I am not the most experienced appraiser, I do know some basic - such as performing some level of due diligence and when asking for appraisals, provide it to the forum, or else don't expect someone else to do it for me, or get much feedback.
Best Success in All Your Endeavours!
