I have been experiencing very disruptive ads when browsing PPRuNe on my mobile. Once a thread loads the page redirects to an ad which appears to spoof a google website and threatens that my handset is infected with a virus.
Of course I know a spoof ad when I see one, my two issues with them are:
1) Pressing back on the ad either loads a redirect that takes you back to the ad, or closes the tab completely. I can't go back to the thread I was reading as the script which loads the ad seems to also close the tab with the forum thread in it!
2) The ads abuse javascript popups and the vibrate API in HTML5. Yes, these dreadful popups actually make my phone vibrate loudly until I close the tab!
Ad domains change all the time but most recently I have seen ads from
lp.want-to-win.com
secure.mobieblitz.com
Very annoying and I hope to see the admins take steps to remove them.
