Health and sanity issue
Why is google allowing rapidly flashing ads on the right side of my email. They make me feel sick and are probably a major problem for anyone suffering with epilepsy. Please ban them before you do real damage to someone. I for one will NEVER buy from any advertiser using these.
Re: Health and sanity issue
Google doesn't allow these ads. As per the Image Ad policy here: https://support.google.com/adwordspolicy/answer/176108?hl=en
Strobing and flashing
Google doesn't allow strobing, flashing backgrounds, or otherwise distracting ads.
If you see them again, I would encourage you to report them under this policy. You can report using the URL here: https://support.google.com/adwords/answer/176378?hl=en
Hope that helps.
