First, I contacted them via this form: https://help.twitter.com/forms/general?subtopic=suspended. In the description of the problem I told them that the number in my Twitter account is my old number, I forgot to change it, I don’t use it anymore and I don’t have access to it. I asked them is there any other way to confirm my account without my old number.
Then, they replied to me with what seems to be an automated message:
Your account appears to have exhibited automated behavior that violates the Twitter Rules: https://support.twitter.com/articles/18311.
In order to continue safely using Twitter, please follow these steps:
- Log in to your account on the web or open your Twitter app (iOS or Android).
- You’ll see a prompt letting you know your account has been locked. Click or tap “Start”.
- Select your country/region from the drop down menu, and then enter your phone number.
- Click “Send code” and Twitter will send you a text message with a confirmation code (note that your standard message rates may apply).
- Enter the code you received in the “Your code” box and click “Submit”.
- You will see a confirmation message that your account is now unlocked.
Once you confirm your identity, it may take up to a few minutes for your account to be unlocked.
If you’re still experiencing an issue after confirming your identity, please reply to this message and provide us with specific details of the problem you’re experiencing. We’ll do our best to help!
Then, I replied to that automated message, saying:
I can’t follow the steps you told me because your system didn’t allow me to change my number. The number in my Twitter account is my old number. I forgot to change it, but I don’t use it and I don’t have access to it anymore. So, could you please provide me a solution to confirm my account without using my old number?
After about 6 or 7 hours, my account was unlocked and they sent me an email saying:
Your account is now unlocked, and we’re sorry for the inconvenience.
Twitter has automated systems that find and remove automated spam accounts and it looks like your account got caught up in one of these spam groups by mistake. This sometimes happens when an account exhibits automated behavior in violation of the Twitter Rules (https://twitter.com/rules).
Again, we apologize for the inconvenience. Please do not respond to this email as replies will not be monitored.
That’s all what I did. Hearing that big social media like Twitter or Facebook tend to ignore complaints, maybe I was just lucky, lol. But I’m glad I could recover my account.
