Youtube auto subscribe link

A couple a months ago youtube patched a url that if you went to the link it auto subscribed to the channel. Here is the old link

http://www.youtube.com/subscribe_button?ch=USERNAMEHERE&bl=ncount&hl=en&action_render_pop=1

Does anyone know any way around this? Or have any ideas on what will work?

youtube.com/channel/CHANNELNAME?sub_confirmation=1&hl=en&action_render_pop=1

i think this is working but there will be a popup for confermation

You mean if you follow some kind of links it auto subscribes you to the channel? I couldn't imagine that YouTube will also become irritating.
