Changed removal of promoted tweets, now using CSS to "hide" the element rather than removing it entirely. Removing it seems to often break twitter, leading to an error message that says "Something went wrong. Please reload". This was apparently due to Twitter freaking out when promoted tweets were removed. Unless… unless of course this was an intentional error, that was triggered when the ad removal was detected? Who knows. Either way, now that they're being hidden with CSS, Twitter no longer seems to show this error as frequently as it used to.
