Thank you for pointing out the typo. Unlike Facebook, it is not possible to grant individual permission to Twitter App in application console. There are very few options available to manage Twitter App permissions. But we don't post or follow anyone on behalf of users without their prior consent. Many other websites like Product Hunt have the similar Twitter permissions list (https://www.producthunt.com/auth/twitter).

If you still do not feel comfortable with Twitter login, you can login via Facebook which has minimal permissions.

At the moment, it is not possible to accept startup submissions via email or a form. It would make things quite hard to manage for us. We want to create an active community and not just merely a startup directory where you list your startup for a backlink and then forget about it. Startup listing is just a part of our future goals at StartupBase. There will be many more things.
