From F-Secure blog:
As I reported yesterday, Twitter suddenly removed my account without explanation.
They have now unsuspended the account.
I also received this explanation from Twitter last night:
I’ve unsuspended your acct.
You were suspended for using the malware URL rnyspeceDOTcom in DMs.
We scan evrythng for malware.
I thought Twitter is fun to use? That’s no fun! I don’t twit and will not tweet 😀
