Just seems like GGP is trying to avoid being hired by a string of people not detail oriented.
I'd add that recruiters that spam people without any criteria or attention are a telltale sign that you are already expected to be treated as disposable and unworthy of attention even way before you are even made an offer.
So, strong start.
I wish recruiters would do the same. If I engage with recruiters that use the scatter gun approach then it is inevtable that they will be wasting my time as they just aren't interested in detail and effort.
