Ah, interesting. I wonder why some plugin avatars are blocked by uBlock Origin and others are not. For example (just random):
Blocked avatar:
https://www.ads-software.com/plugins/ga-google-analytics/
https://www.ads-software.com/plugins/klarity-message-action-block/
https://www.ads-software.com/plugins/ads-wploginmenu/
https://www.ads-software.com/plugins/securimage-wp/
https://www.ads-software.com/plugins/logout-clear-cookies/
Not blocked:
https://www.ads-software.com/plugins/banhammer/
https://www.ads-software.com/plugins/customize-snapshots/
https://www.ads-software.com/plugins/wp-author-slug/
https://www.ads-software.com/plugins/wordpress-2-step-verification/
https://www.ads-software.com/plugins/webdesignby-recaptcha/
No idea why uBlock would block only some of the icons? Some of the blocked images are JPG, others are PNG. Really bizarre..
Even more interesting is that some of the larger banner images are blocked and others are not, so there does not seem to be any logical pattern or explanation as to why uBlock is blocking some images (types/sizes) and not others.
