Group refresh buttons

Hello there,
I have a rather annoying problem, in my group, I have 787 members counted by on sg, but on the official group page on steam, there are actually only 599 members. Who are these extra members? People who have been kicked, months ago. I often go through the pages to catch people who are using the group improperly, and when I see multiple people on EVERY PAGE that are inactive, it's annoying. (going through 188 extra members, just to find the inactive ones still in the group.)

So, I thought of a solution that I think would be welcome.
Could there be Group refresh buttons? One for every group, for only the creator of that group to use to force sync everyone's in the groups accounts here on sg, at least once a month. So you could only click the button once a month, (or three months) to clean out the inactive members.
OR give support members the ability to force sync groups via ticket request.
OR have permabanned SG members to have their "groups" reset/zeroed out upon being banned.

If you have any additional ideas, I would love to hear them, or something to add on.

Please consider this. Would make life so much easier.

Also, if you could please bump the topic. <3

Thanks for reading!
