Removing crafted by on items

[JD408]

not sure if this is a exploit, bug or guide, but I'm going to share it here.

I found that putting items in my guild bank seems to remove crafted by from the item after a while.
How long is what I am unsure about. I haven't watched it closely since it nothing important.
What I noticed is crafted by toons with accent marks in the name seem to remove faster than crafted by toons with no accent marks in the toons name.
the accent mark toons names seem to get removed within a few days.
The ones with no accent marks I am totally unsure. I didn't even think it was possible until today when I found names finally removed.

I've only tested this in guild bank and not personal bank and it was with Hexweave bags. I haven't tried other items yet.
