I am not sure why his posts disappeared, he did delete them himself (I think), but I don't think he was banished or censored... he should not be in my opinion.
Speaking of this rifle alone, not the description or his general activities, he did not alter this rifle, I have prior records of it and it has been in this condition or state since at least 2003. It has been apart before also, while byf couldn't disassemble it, it has been before (I don't doubt he tried, he usually goes way overboard taking pictures and disassembly, so it is reasonable that he simply couldn't here)
Anyway, while I do agree a 20% restocking fee is ridiculous and excessive in this case, I do not agree byf is some turd monger or disreputable seller/flipper.. I observe his auctions routinely, no evidence exists that he alters rifles so far as I have followed his sales. He may be a flipper, maybe an opportunist, neither are crimes or immoral, he does an absurd number of pictures, he seemingly hides nothing (typically he takes huge numbers and total disassembles, in this case it would not have made a difference had he, the flaw is clear without disassembly imo) and I have nothing against him or his presence here.
