Streaming service Twitch has updated its terms of service to crack down on the amount of "sexually suggestive clothing" being shown off on the platform.
The company states that anyone wearing no clothes, or simply items designed be suggestive, now risks a channel suspension.
The list of banned items includes "lingerie, swimsuits, pasties, or undergarments" as well as "any full nude torsos".
"Nerds are sexy," the new Twitch terms of service explains, "and you're all magnificent, beautiful creatures, but let's try and keep this about the games, shall we?
"You may have a great six-pack but that's better shared on the beach during a 2-on-2 volleyball game blasting 'Playing with the Boys'."
But maybe it is hot and you want to take your clothes off? Maybe you like doing that even when it is cold? If you feel such an urge coming on then you should simply "crop the webcam to your face", Twitch concludes.
"We sell t-shirts, and those are always acceptable."
In August, online retail giant Amazon snapped up Twitch for an eye-watering $970m. Google had also been close to brokering a deal.
Twitch also recently tightened its policy on paid-for or sponsored content in a bid to be more transparent - although will only enforce disclosure on deals in which it is involved.
