Even with an adblocker it makes mire than half the page blank and the bottom banner completely blocks the last comment if the comments thread has more than the normal length of the page.
Submitted feedback about this issue this morning, the ads in-between posts are bad enough but there are now banner ones which cover half the screen, ridiculous!
An alternative (that wouldn't work unless a lot of people follow through), might be to contact advertisers and inform them that the way FS implements the ads gives a negative perception of their brand. The new owner won't care until it causes a loss of revenue.
Then again I'm on the mobile website, maybe it's different in the app.
