Description:
It would appear that I cannot rollback anonymous users through the API.
URL:
http://en.wikipedia.org/w/api.php
Post data (percent-encoded):
action=rollback&format=xml&title=User+talk%3aGurch&user=86.140.177.30&token=f88492c3c482f3f322a9f336faba934a%2b%5c
Response:
<?xml version="1.0" encoding="utf-8"?><api><error code="invaliduser" info="Invalid username ``86.140.177.30''" /></api>
Reproduced in other formats on other pages with other anonymous users, also tried percent-encoding the whole username.
Version: unspecified
Severity: major
