Banning the accounts that solely exist to promote other social media sites is the equivalent of your example. Banning any links whatsoever is more like Walmart kicking someone out for even mentioning Target. The former is reasonable, the latter is retardedly over the top.
It's hard to make a comparison using the analogy at all, even, since Walmart is not intended to share information. Twitter - at least in theory - is. It's for people to promote themselves! People have always included links to where they are on other platforms.
