This guys are really stupid, and as many mentioned, probable a SCAM (office is virtual, phone is non existing, domain is 1 month old etc.)
BTW I am pro forking to 1MB SIZE, although their test is really retarded!!!
I have been using Bitcoin for 3 years now, and rarely have I send a transaction without fee and volume lower than 0,1 BTC, which means, that the 8500+ clogged transactions are only their own, mine and most other people transactions went thru with little to no delay.
A backlog of ~6k transaction is pretty common durring "prime time". My only problem with this is that its not helping anyone. They are a dick to everyone using the network just to prove a point that is already well established.
