Banned members should be indicated on their profile summary

What are your thoughts on this?.

You can easily add indication for all banned and archived members (with many other additional goodies) if you install BPIP extension in your web browser.
Maybe this is not as elegant solution as having direct forum code changes, but it works fine.
You can find more information with links and instructions in BPIP extension ANN topic:

PS
Note that you first have to enable this option in extension settings:

The last data I have is from August 2023 (and I'm not planning to update it again).

It doesn't matter, we still have Top senders to permabanned users, last 180 days and anyone can know it and access it anytime. Complete data or full list data may only be needed when someone comes with curiosity, but of course this is not an urgent need. Such users probably won't come twice a year or that often, so this will save you space.
