If you are the recipient of the link, SSL can't be stripped.

Even if you are an author, assuming you have visited the site over SSL at least once, then it can't be stripped on future visits since the site seems to use HSTS.

It is trivial to strip links being sent to a user over unsecured channels.

There are many things that can mitigate an sslstrip style attack, but coverage from those things is patchy.
