The Clickers and Wordlinx: PTC Scams?

Okay, I've been using TheClickers.net and Wordlinx for weeks now and though I didn't earn money as quickly on TheClickers as I did on other sites, I've been trying to be loyal to it. However, recently I cannot even log onto the site. Everytime I try, my web browser says that its unavailable.

On Wordlinx, I am still able to log on and click on advertisements but the .5 credit ads keep bringing up a warning/flag. My web browser claims that the pop up ad is unsafe and that there is a computer threat attached to it. So for the past three days I've only been able to click on 1 credit ads which has limited my daily earning.
