Issue WP-toolkit smart-update-screenshots disk usage

[Nick]

Is there a way to prune/remove the wp-toolkit smart-update-screenshots? We have a large number of WP installations on a server and the screenshots are using 56GB of disk space. That could be better used for site data instead of screenshots. Are those safe to remove? Is there a way through Plesk to limit the amount of space used?

Anyone have any idea on how to clean these up? I'm at 70GB in the smart-update-screenshots directory now.
