> Worse: if the user's UA “clicks the link” by making the GET request to generate a preview. You mean something like a popover preview that appears when the user hovers over a link? Isn’t there a way to configure the `a` element so the UA knows that it shouldn’t do that? | ||

If sending just HTML you could include rel="nofollow" in the a tag to discourage such things, bit there is no way of enforcing that and no way of including it at all if you are sending plain text messages. This has been a problem for single-use links of various types also. So yes, but not reliably so effectively no. | ||
