Trade of a squelched user appears on my search

Device:
Notebook Dell
Browser:
Chrome
OS:
Windows

Steps to reproduce:

I searched for a trade, and commented on it. After that, when I looked at the BattleNet Id of the user, I remembered that is the ID of a user that I squelched a while ago (I note that info on a personal file)
But the user now has a diablo2.io login different from the one he had when I squelched him...

I went to my squelches list and the user was there (but with new diablo2.io login and not the old login he had when I squelched him...)

Seems like the squelch feature does not work 100% when the user change his login

Anything else to add:
-

But the thing was that:
I squelched him with the "old login"
And when I open my "squelched list" the "new login" was on the list instead of the "old login" (apparently the site updated the login change on my "squelched list" - OK)
Actually, the user changed login again, and the "new login 2" was automatically on my "squelched list" (OK)
But while the "squelched list" is being kept up with the login changes of the user, the trade filter (that should hide squelched users - for what I understand), seems to not work when the user changes his login, and fix trades appear on search results (that is the issue I'm reporting)

Ahhh okay, must have been a username change then, which the filtering hasn't caught up with. Just remove them from squelch list and add again, should work.

I tried that... un-squelshed him, then squelched him again (from his user page).
But his trades keep showing on my search results....
I even done two different searches, to discard recently cache of my previous recent searches.

(just to be clear, I don't hate the guy , I'm just reporting a possible bug )

You need to give it 1 hour for any changes to take effect in your market filtering. Did you wait 1 hour?

I will try latter
(I thought that just do a different search would be enough...)
