Sorry to hear that, sounds frustrating. Can you please send us a screenshot of that obtrusive behavior? Posting here or sending to [email protected] would be awesome.
That's weird, the URL mentioned has nothing to do with Imgflip. Could be from an ad provider. I don't think it is dangerous--Heroku is a fairly large service. Does this pop-up take over/break the whole page forcing a page reload, or are you able to X out and continue?
Thank you for reporting. Do you happen to have a screenshot that shows the whole page? If you see this ad (or any other misbehaving ad) again, please try to take a screenshot of the whole page so we can see how it is positioned and I can report to ad provider.
