I would imagine it was disagreeing with Spie's views on a few things and being somewhat forthright. Doesn't matter, don't care. I'm surprised this account is now unbanned TBH - I only looked it up as I'm over a fellow OcUKer's house and this forum came up.
I was a mod over on SciForums for the better part of 10 years but stopped a while back. I finished my degree, got a masters, completed a PhD in the non-perturbative symmetries of Type II compactifications in string theory and have worked in mathematical research/applications in the private sector since them. I've solved quantum mechanics and satellite design problems for the European Space Agency, AI problems for the Ministry of Defence, oil well modelling for a major Oil company and written/presented educational material in several major universities. I won't say my current employer but what I do is something everyone has heard of. I now live in London with my gf but we don't have kids or anything. Still friends with a few other OcUK mathematicians from back in the day - 3 former OcUK members are within 3 metres of me as I type this.
