--- Comment #1 from Kunal Mehta (Legoktm) legoktm.wikipedia@gmail.com --- My crystal ball suggests: * Wikitanvirbot is running from the toolserver, which has a patched 2.7.1 without unicode bug * TXiKiBoT is running an old version of pywikipediabot (there is no python version in the edit summary) on python 2.6.5+
Conclusion: TXiKiBot should be blocked until its owner fixes his/hers setup.
