[Suggestion] Add a Custom Word Block/Filter Feature for Chat

I'd like to propose a feature that I believe would really improve the overall chat experience in both Path of Exile 1 and 2.

Feature Request:
A custom word block/filter system where players can create a personal list of words or phrases. Any message containing those words would be automatically filtered out or hidden from their chat.

Why this is needed:
Lately, chat has been flooded with spam, especially from RMT sellers. It's becoming a constant annoyance, and a feature like this would give players better control over their own experience without relying entirely on report systems or global filters.
