London, Feb 26 - Singer Lily Allen slammed twitter.com for a second time - branding the social networking site as 'dangerous', even though she has started using it again.

The singer is wary of becoming too attached to the micro-blogging website because she doesn't want to become self obsessed, contactmusic.com reported.

'I sort of 'tweet' here and there, I don't do it as obsessively as I used to. It is very addictive and quite dangerous.'

'I think it can turn you into a sort of self obsessive (person). Why do you think that people would want to know everything that you're doing? It has got negative connotations, I think. But saying that, it can be quite fun. It's a way of communicating.'
