It's unfortunate that you're letting one person ruin your entire experience. Sure Mo and I haven't seen eye to eye on everything, but at the end of the day, it's just the internet. We can co-exist and agree to disagree. Granted, there are plenty more things that we do agree on and find in common, and it's those things we tend to gravitate towards. I'm not saying you have to be best friends with the guy, but you can choose to let things get to you or not.
In terms of the 4-5 regulars, yeah, PHF is built of a common core group, but I have to disagree when you say we 'go off on everybody that registers here'. There are some users who recognize people from across different forums, and maybe they had beef on another forum, so they'd pull their claws out seeing the person come here, but that doesn't happen to everyone. Once again, you have the ability to choose what your microscope is focusing on. I personally choose to put things that interest me under my microscope, and I do my best to weave out things I don't care for, like all the leak drama. When all that shit got onto SoundCloud, yeah, I was peeved that everything I traded for, got leaked, but it's not the end of the world. I choose not to get involved with the aftermath cause it doesn't do anyone any good.
To summarize, you have the ability to choose what you accept as truth and what you respond to. It sucks that you and Mo got into an argument, but there's more to this forum than one person.
