Expand voidlist to hide player's name entirely

[Naixatloz]

There's a person in this game I do not want to see any trace of. Even though I have them blacklisted and voidlisted, I can still see their name in certain contexts, such as:

• Market sales history
• House owner list when using residential district aethernet
• Message book comments
• Signature on crafted items

Is it at all feasible to hide their name in these menus? Or even better, replace it with some randomized filler name so it's not a conspicuous blank space that reminds me they exist.
