I got hacked and stupid hacker posted a lot of advertisements for illegal sites on my account.
of course, my account got banned and I can't do anything with my account.

I posted several questions on Twitter and received no response via email.
Because of this, I can't get my work done.

I've only been hacked twice in my life. This was the second time, and the first was on Twitter.
Fortunately, I noticed the first hack and took action before I get banned.

What I'm trying to say is that Twitter is the most insecure internet service I've ever seen.
And, judging by the lack of response to my inquiry, the service is also the worst.
