To be honest, you have to remember that the scan groups are not all-knowing gods, and that they have to look around to look for relevant information to ensure that the manga is more accurate in its description. This ensures that others working as the MC's occupation (e.g. pottery enthusiasts) will be happy that their trades are not forgotten, and still remembered via the usage of these terms.
That also means that they may have trawl through Google to look for pottery terms and such. Maybe that is when your blog/webpage might have struck out as applicable/reliable to be used as TL work.
However, if you believe that there is a need to set things straight, you can technically DM the staff members to ask to be credited for some of your info being used on the last page or sth. (although I'm not sure if that even exists)
