I was wondering how much it costs to open a company in the UK to do something like that, and it seems to be really cheap (and quick):
a) Incorporate directly via Companies House
The standard registration fee to set up a company is just £12 for the ‘standard’ Companies House web incorporation service, which takes up to 24 hours to turnaround. You can pay via credit card, debit card or PayPal.
I'm disappointed that the discussion seems more about debating whether that person acted in good faith or that the law regarding acceptable characters in company names should be changed, as opposed to the bigger concern of why were they not sanitizing company names? Even without intent to insert HTML, characters such as < or > would still break their pages.
