As a user who sticks around on the forums for a while (read: likes to keep a tab open) I find the DDoS protection breaks the experience of using the site. Unfortunately, pressing back or trying to go to a different section of a site after coming back to the tab doesn’t work. Instead I get “oops, sorry.” All I can do is then reload and start from the current page or even the forum main page.
Perhaps we can change the setting back to what it was previously!
