The F means "fanned" you and the W means "watching" your auction. It's a positive thing. The more people watching generally the higher the bids. At the very least it's a show of respect for your auction, so to speak. Badges can be earned by having a certain number of fans as well as a certain amount of watchers on a particular auction. Sorry if I alarmed you : ) Good luck.
You're welcome and sorry for the question just asked you. Apparently I can't look at a photo very well today : ) I clearly see the SD card in the photo!
Also there's a tiny "reply" underneath each comment made. Click or press on this (if you're using the app) and you can reply to each comment. You can also choose to hide one if it's inappropriate. It's really good to reply to everyone's comments, so the guy who wrote and said he fanned you, was watching and to please fan back. You click reply and say, "Thanks, or Ty, fanned back". You will run into some nice people on here and some ignorant as well : ]
