Suspicious and disruptive redirect from forum thread to "ad"

[snakestu]

Forum URL: (private)

When viewing a thread on the forum at the (private) URL provided, I kept having my browser redirected, in the same tab so taking me out of the forum, to the page shown in the attached image. I usually leave Ghostery turned off for the forum to allow for ad revenue, but had to turn it back on just to continue using the forum without this disruptive and suspicious behavior. Once protected again by Ghostery, the redirect did not occur. There is nothing in the thread itself that would cause this, it is clearly coming from an ad presented by the forum itself.

Hi

Apologies for the inconvenience this has caused. If that redirect was caused by one of the ads, it should already have been flagged and if not already taken out of the system, should be soon. If you continue to have the problem, could you let us know

Hi Craig,

I'm getting the same redirect from my forum, as well. It changes depending on what service provider I'm using at the time. I was redirected at 10:15 EST.

Hi Craig ,

I'm getting the same redirect from my forum, as well. It changes depending on what service provider I'm using at the time. I was redirected at 10:15 EST. 

I have the same problem as well from bsn.boards.net for about a week, and as described, the redirect page uses the service provider's name depending on the network that I am on. I cannot tell which banner ad did it because when the redirect page loads, the back button in the browser no longer works so I cannot go back to the original page. I have to close the browser tab and re-open the forum website.

This is the screenshot from yesterday, but this morning this page loaded with the top URL "globalaccountingfirms.top"

Hi,

Thanks for the report. We had a hard time tracking this one down but we believe we have this blocked now.
