A "clear all profile scribbles" button, or even a system identical/similar to the one managing deleting personal messages would be super nifty for players like me who still have profile scribbles dating to 2011...
It gets a bit hectic and time consuming attempting to delete each individual scribble on my page.
I do understand me and my laziness are at fault for my long list of scribbles, but I'm sure I can't be the only user with this issue.
I thought this idea would be at least worth throwing into the suggestion forum.
