I strongly disagree on that. The fact that you have an account behind it doesn't make it attributable at all. There's nearly no verification on 99% of the internet. Some studies consider that 9 to 15% of Twitter accounts are litteraly fake . TwitterAudit believe that 40-60% of Twitter accounts are fakes.
They aren't attributable to anyone except a username, which is worthless.

It was never about code execution but what they call "wallet code" which is what I did in another comment .

You can easily register a domain anonymously. Most links are fine sure, most possible domains, aren't, which is my point. Show a warning (which they do on URL Shortener) instead of blocking a domain altogether on ALL links and use a white list (which would include MOST used domains) instead.
