There's something on the main page which slows down the browser to a crawl and makes the site completely unusable, you can't even input your Bitcoin address or the CAPTCHA.
I think it's some ad, because it happens sometimes but not Always; this has been going on since yesterday.
Please fix this ASAP.
I suspect it occurs by a-ads.com banners - removed from main completely
I can confirm this only occurs when a specific ad is displayed (something about bicycles); however, the ad is in my language (Italian), thus it's probably user- or location-specific, and reproducing it would be quite difficult. The only thing i've noted is, this ad is always displayed on the left vertical ad panel.
And yes, this keeps happening; it just happened again a few minutes ago; also, it can happen both on the main page and when playing the game.
