Let me instill some common sense into this
No NWS office is going to pop a tornado warning on a cell that doesn't look capable of having a tornado -- based on a single report. Even if it came from your group, they just aren't going to pull the trigger. If they get two reports, then it's another story.
Note that Tyler said "bad report" - not "intended to cause malice" report.
No, it's not saying that at all. Have you ever tried to estimate wind speeds in a storm? Everyone is horrible at it. So technically they are "bad" reports. People should only give the conditions that lead them to estimate those winds -- but my guess is that when your spotter calls in E60mph winds you pass that right along to the NWS. You are relaying a bad report... but I'd rather have a bad estimate, which I can go back and interrogate using SN, than nothing.
That's not what you said a post prior... You said specifically in the first line that you check the report for accuracy.
This is a response covering rdales and Tylers postings:
Terms are getting crossed up some, I agree.

I did say accuracy, but you can increase accuracy with the methods we use. The method is vetting reports submitted to us for relaying to the NWS.
Examples: during an event last summer, we had a unknown ham radio in a report of a rotating wall cloud in one of our counties.
At first he gave his position on the East side of the county, 5 minutes
later his location changed to the West of the county.
Not possible. We questioned him further and it became clear that either
he didn't know his butt from a whole in the ground or it was not a real report.
We did not submit the report.
Spotters must use a preset reference points that is selected by folks at
our WFO here. These points are marked on the radar screen, both
at the NWS and our base GR programs.
If a spotter turns in a report of hail, gives the reference point, but the radar shows clear sky above that position and nothing near them then we vet the
report further. Perhaps correcting the location information or discrediting the report.
But, lets say someone we do not know comes in with a report, sounds shaky, stumbles during the report, does not use the preset reference points but accuracy street directions and says they see a lowering, we question them further to see if it is a tornado, a funnel cloud, a wall cloud, if so is it rotating etc. Not only allowing us to "hear" from that if they are actually seeing something and what it is.
So by assisting, vetting and verifying the report (as much as we can) we
improve our "accuracy of reports". This is tracked at the WFO.
You do not have to be a Met to see clear skies or that something in the report is not correct.
You may think you are helping your WFO by passing on any and almost all reports but during an outbreak it will become an issue.
When the NWS sends out a team and they can not find any sign of a tornado or the reported weather event it causes folks to doubt you. They may not say it but it is there.
Our vetting of reports (as much as we can) increases out accuracy which
allows the local EMM to trust us and to act even before a warning is issued.
To me that is a major plus in increasing lead time on getting some sort of warning out to the public.
No report is better then a bad report, simply means know what you are looking at before you report it.
It seems the SN test is an attempt to do this, so why shouldn't we?
Tyler, I think your test is a good thing and the fact that it is there
indicates you are doing the very thing you do not like us doing
Otherwise you would not limit access to the SN reporting system by
using a pretest screening method.
Yes, we need to be sure that we did not hold up a report simply
because we 'think" it is bad. If there is any question we pass it along
but indicate we are seeking further information. Leaving it to the Mets
as rdale said.
But it is the Mets that are training us, instructing us and providing us
with training to do some of the vetting and removing some of the unneeded
static that occurs during a severe weather event fire fight.
We may have to agree to disagree on some points, but in the end all
have demonstrated a desire and willingness to further their ideas for
the sake of saving lives.
This is good.
