What I find most problematic about the attac is the incident response by Twitter. As people pointed out here, hijacking Twitter accounts can lead to big stock market crashes, mass panics ("bomb found at XXX") and maybe even military escalations. Under this circumstances, leaving a platform with an unknown number of compromised accounts online, seems irresponsible to me. In such a case you must stop the bleeding ASAP, either by locking up "important" accounts (what they eventually did, after a few hours!) or taking the site offline. Next time this happens, we might not be so lucky.
