Auto Subscribe to threads
 

I am wondering if Auto Subscribing to threads users reply to is good or bad. I know that all the major websites have this, like Google Plus and Facebook - It is great for getting users back to your site, but I am curious on other vbulletin owners thoughts on this. I personally have a small site, so I havent received a single complaint in since I have started the forum, I think my site has grown and benefited from this feature, but what about you?
