What Is JAV.GURU Using as Their Server Button

[momomesh]

hi guys,

I came across JAV.GURU, they're prominent Japanese adult site,
I found that they're using some kind of code to mask their embed links from DMCA bots,

anyone know what plugin are they using or is it a custom code?
if you can provide me with the service kindly post or pm me please~

Thanks
