Watkins made it a priority to combat "piracy" of 5channel by third-party "matome" sites in March 2014, adding "tensai kinshi" to many popular boards. Such sites siphon users from 2channel itself, with some receiving in excess of 100 million monthly pageviews; in one case a "matome" site earned its owner per month. Watkins followed up the rule change by restricting access to 2channel's data in March 2015, by requiring that dedicated browser authors use a special API to access 2channel's, and later 5channel's, thread data.
