He was very well known for being an HF member who was involved in a project regarding the production of movement bridges that could convert cortebert movements into rolex 618.
then all of a sudden he turned against the project and forum, denying his involvement, and started to share his investigations on vintage watches on 'Risti. It all went well until he decided to put in doubt Ehlers and Wiegmann's reputation (they're the guys who wrote the vintage Panerai books - a bible essentially) and as it was not enough he also questioned authenticity of one of the most famous 6154, owned by one of the most known and respected paneristi members.
At that point his real identity was exposed and he rejected his link to the homage community and focused on his nice website.
Lately he put up a crusade against the Rinaldi's and a well known vintage rolex opinionist (I think his name was ocho-something). The two guys went very low in their exposing each other, a disgusting show that included private life pics.
All in all his investigations are interesting but his findings are to be taken with a grain of salt. The guy has no respect for others and deserve the same imho
