 :I'm not exactly sure what more I need to comment on. It is clear that this user is here for the purpose of promoting his/her website. His non-spam contributions are strange (a lot of __NOTOC__ additions) and probably just being used to camouflage his primary spam purpose. Without a clear indication that his spam will cease there is no use unblocking. And in any event he needs to change his username because this one violates policy.
