I decided to create a twitter account to see what's going on there.
I searched for posters that I used to follow, all suspended, "Does not Existed", etc.
Then, (based on my searches I think), twitter blocked my account unless I entered a phone number.
Happened to two accounts, one from a US IP, one form a European IP.
It had nothing to do with your searches and everything to do with you not giving them an "Oh, but it's optional" phone number.
Twitter has been doing that for a long time. They WANT a phone number because it's easy juicy info to help tie you to a real person.
