Half of your hotlists tell you your activity on the site. Every time you look at or contact another member, it shows up on your hot lists and the numbers go up accordingly.

The other half of your hot lists tell you about the other members looking at your profile, emailing, or teasing you. Every time someone looks at your profile or contacts you, it shows up in your hot lists and the numbers go up accordingly. Keep in mind, however, that some members choose to hide their profile from showing up in your hot lists.

Also, in order to keep your lists up to date, we periodically clean out the members that have been in your viewed lists for a while. This also changes the counter.
