Many online bulletin boards require users to be signed to write—and, in some cases, even to read—posts. 2channel and other Futaba-based image boards take an opposite stance, encouraging the anonymity, and in the case of English-language Futaba-based websites, calling those who use usernames and tripcodes "namefags" and "richeys", respectively. As required by law, even communities such as 4chan do require the logging of IP addresses of such anonymous posters. Such data, however, can only be accessed by the particular site administrator.
