The following statement was received from ValuClick today:
ValueClick pop-ups were appearing on the PPRuNe site on the morning of Thursday the 23rd May. There was a technical fault, which automatically linked one of the pop-ups for a campaign to certain banners. The pop-up should not have been linked to the banners. It is not our intention to serve pop-up campaigns to sites that do not wish to show them.
We were made aware of the problem through contact with some of our publishers at 09.45 GMT on Thursday. Our technical support team solved the problem by 10.10 GMT. Since then there have been no reports of this problem reoccurring and we have been monitoring our network for any problems.
The PPRuNe website has never requested pop-up banners from us and it is through no fault of theirs that this problem occurred. We are sorry for any inconvenience caused to both the PPRuNe website and to their users.
