I'm a member of hundreds of Facebook groups, which I enjoy except for the fact that their owners sometimes send me a direct email. The result is dozens of direct emails that I can't seem to find a setting inside Facebook to block. So then I move to my Gmail filters. Is there a way to filter out the Facebook group mails using Gmail filters? The identifying feature of mails from groups is that their subject header contains quote marks, so the sender is always Facebook and the subject header is always: "Group Name" sent you a message on Facebook. My question is: how do I teach Gmail to distinguish between these mails and mails from my actual friends, which don't have the quote marks around them?
When I favourite a video on YouTube, it turns up in my Facebook feed. Same with Last.fm - when I favourite a track, all my Facebook friends can see. Apparently at some point I synchronised Facebook with YouTube and Last.fm. The problem is, I don't know how I synchronised the accounts, so I can't replicate it or show anyone else how to do it for themselves. Can anyone advise?
