I've had him on ignore for months; I suggest everyone else does the same
I rarely put someone on ignore, but my patience has its limits. We have shown him evidence of Wasabi being flawed so many times that it has become tiresome. Every single time he ignores it and blames his competitors.
He's welcomed in my ignored list, but I suggest everyone to keep a gentle warning when encountering a wasabi shill in a random thread. Newbies should be informed about both sides of this drama, and make an informed decision based on compelling arguments.
