I have received the following message from FM.
As of 10:00am today the supplier who we suspect of putting the re-directs out on the network has been suspended from all forums for a 24 hour period.
If you still have problems can you
1. To report any re-occurrences
2. The report should include, the device viewed on, the time the ad was seen, the type of ad seen (a pop-up is different to a re-direct)
3. A screenshot of the advert (if possible)
Could you please email m4morris@clara.co.uk with any incidents or PM me (if you can)
Hopefully there won't be any issues (for 24 hours at least)
