Today has seen a jester register the http://twitter.com/sirfredgoodwin account to poke fun at Sir Fred Godwin, former Royal Bank of Scotland ceo, who suffered in the press recently for plans to receive a hefty pension from his former role at a time when the government are bailing them out.
It raises the interesting issue of how long it will take for Twitter to tighten up the procedure for registering accounts. There are a few examples of Twitter squatting on famous brand names, such as http://twitter.com/coke
It seems only a matter of time before a big brand, or famous name, complains about such activity. At the moment no email verification is required to setup an account so it is very easy to setup up numerous accounts. With the website becoming more mainstream some form of domain name style system seems an inevitable step, maybe even a way for Twitter to make some money.
