Perhaps it exists: An addon to manage the guild bank against junk deposits
 

I like the idea of keeping depositing to the guild bank an option for everyone but managing it seems like it will be huge.

Perhaps a way to auto withdraw items that don't meet certain requirements, like anything not champ 150+, nirnhoned, or legendary.

Even just having an addon that adds a visual element to each new bank item since last it was checked out be a great way to quickly get rid of the junky stuff for selling for guild gold.

Maybe there is an addon for the issue already?

As soon ZOS will do something against Guild Bank stealers, I'll do it, meanwhile I recommend to everybody to do not write something like this.

I'm using AdvancedFilters at the guild bank to select "unwanted items" and move them all to my local pockets + destroy/sell them.

For my local Bank:
In addition I'm using "DoItAll with FCOItemSaver support" addon to "Bank all" items with one click -> move all items filtered with AdvancedFilters (only visible will be moved) to/from your bank.


For my guild banks:
I do the same but with the "Move all items" addon
