This is not being detected by any Gmail filter. Every message got an attachment with pdf and picture inside. I think the picture in Pdf is loaded dynamically from other source, so they can see if I opened the message. Is this even possible?
You're being targeted.
Yes, they can use pixel tracking within the email if they really wanted to.
Gmail won't block these, mark them as spam and that's all you can do.
I've also had Tibia account login failures for the last 5+ years, every month or so it'll send me an email xd
I get a shit ton of spam daily, all with pdf attachments etc, I just junk them if I can be bothered or delete them and move on. Without a dedicated spam filter (Mimecast etc) you won't get rid of them.
