Normal images in a group post, not babes. Not blocked but being logged out of the bot (and manual posting) and having the "looks like your account was compromised" message. Change password and all ok. Manually posted the image again in my own groups so it's not a clickable image, just an image, and it's fine. Can't say what the images are but on the national scale such as Ford or Dodge. Big companies brands.
Thats strange, it looks like that fb think your account is legit but have been hacked and used to spam.
