It looks like your friend has been globally blocked. You can recognise a global block by the BLOCKED tag in his user profile masthead, but no block log entry at the top of his contributions, e.g. Special:Contributions/LORD OF DARKNESS. Global blocks are blocks on all wikis and are managed by a different system that runs separate to the normal block tool which means you won't be able to see any log entry and you won't be able to undo it.

It's possible he's fallen afoul of a IP range block that went a bit too far, but I don't think those who up on your profile masthead which suggests he was blocked intentionally by staff or VSTF. In either case, he can write into Special:Contact/general with any questions or an appeal for his block. It does need to be him that sends the message to staff as staff will not discuss global blocks with anyone but the intended blockee.

Hope this helps.
