Because, if so. Then you are commiting a disfellowshipping offence by taking part in bad associations...with known apostates.
I'm sure that if your elders, or CO knew of your visits to this site, they would move promptly to a judicial comittee. Furthermore, you may think that no one knows your actual identity. But Jehovah knows. Why would you brazenly defy Jehovah by mingling with apostates? Or do you really, deep down, harbor some doubts about God's 'true' organization. Well, Jehovah can read those doubts too.
Jehovah aside, one with a bit of internet savvy, and basic hacking skills, could easily find your IP address, and your geographic location down to a few city blocks. From there, it would be simple to find which Kingdom Halls serve your area, and warn the elders that one of it's members, with internet protocol of XX.XXXX.... is a brazen mingler among apostates. Since you probably bring an ipad, or iphone, with your KHs IP address stored in the device for automatic log-in, then it would be pretty easy to check the router for your device's IP.
This could be going on as I type this.
Be afraid, very afraid.
