Yep, I do have very simple non tabled recips...and yup, close to half my submissions have those links colored the same as or nearly the same as the page background. As Mateuz said, does make it easier to weed out those that are either autosubmitting...or just don't bother to look at the freakin page before submitting.
I also don't have any superfluous form fields, though I have seen a few that do. Shouldn't be a big deal to plug in the data and hit submit though.
Agreed on the confirmation codes, I've run across a few of those that are a real pain in the ass. Especially if they refresh and clear the fields
