What? Another one who lost interest on the scene and dared to go off live his life, but at least he bothered to make up a little white lie in the hopes that no one notices.
Happens all the time. I often piss on this place and go worry and screw up other things in my life. Sometimes I stay away for several weeks. AFAIK, no one is obliged to make regular postings here. And if someone moves on it shouldn't mean he should be brought under the microscope.
It's his life, his post count and his own damn business as to why he didn't bother to come back. Keep in mind that there are people here from countries where they are respected, have their own personal privacy, and the privilege to mind their own damn business.
