>as soon as I registered ok Twitter I got a notice about "suspicious activity" and about having to validate a phone number to be able to use the account. At that time (2015 I think, I don't have the account anymore) you could get around that by contacting support, explaining that you don't have a phone number and waiting a few days for them to manually unlock the account. Same thing happened to me last year in the US. The kicker was that they automatically opt you in to product update, daily digest, etc. emails. But those emails don't have a 1-click unsubscribe - the unsubscribe link takes you to your account settings, which you can't access when your account is disabled. So you can't unsubscribe from the emails or delete the account. You can either add a phone number to stop the spam, or search around to find the page where you can submit a ticket (because there's not a support link on the disabled account page) and hope someone gets to it eventually. They never even replied to my ticket, they just silently unlocked the account after a week or two.
