Take a look at their edits that day. They did EXACTLY the same thing "134.161.244.89" did, namely remove comentary that they did not agree with. If you say what they did was not vandalism, then "134.161.244.89" is exonerated too, as all he did was remove the biased revisions of others, who violated the 3rr as well. By blocking the one and not the other, you are being very biased, and bias has NO place on wikipedia.
