[soggy]

Excuse my ignorance, but why would the below sites be showing up in stats as referers to this particuliar page....

/link_list/lesbian.html

All show up as below in my stats and I see no links coming in from said pages. Is something screwy going on?

Thanks in advance! |huh

I got those also, only thing I can think of is some blocking referer program, and they use those kind of urls as a dummy referer

Some refering blocking software use a list of domains like that, and you only need one guy coming in and loading the images off your page to endup with a whole list of bullshit.
