I signed up and was immediately banned after following 3 different accounts in fairly rapid succession. I had already been "following" these accounts for some time by directly going to their twitter pages on the website and had them bookmarked, so I just went to each person directly from the bookmarks and hit "follow." This is apparently "Unusual activity." In order to prove I wasn't a bot and continue to use their service, they wanted my phone number (I signed up through the website and don't want the app on my phone). I really don't care about tweeting myself and it was just for the convenience factor of having the accounts all in a single place without having to go to different bookmarks each time, so it's not a big deal to not have an account. It's all publicly available, although they're trying to make it harder to navigate twitter unless you have an account and signed in.
