We are unable to add a link to websites using the .csc gTLD such as: http://i.am.csc From this post (Creating an application for a .technology url) it sounds like this list is periodically updated from IANA. Unfortunately it has not been updated since last August: https://github.com/twitter/twitter-text/blob/master/conformance/tld_lib.yml A number of TLDs have launched since then. We would really appreciate it if csc could be added to that list. @andypiper is this something you may be able to assist with?
No, I am not specifically able to help with this. I would recommend that you raise an issue against the twitter-text package with the gTLDs that need to be added, and when the engineering team is able to take a look they may do so.
