How low a score does an image need to get a "Downvotes Galore" tag?

I’m trying to make a custom filter that removes most forms of shit posts.

@Xamrin  
A cursory glance at it shows them with scores ranging from -12 to a whopping -520+. However, aside from the one -12 pic, the next step down seems to be in the -30s. I’d set up the filter to not show anything with a rating of -30 and below. Or -20 if you wanna be on the safe side.

Umm… There doesn’t appear to be an option for that in the edit screen for the filter.

@Xamrin  
Oh, it’s not there. It’s the first thing on your Settings page. Just click the tab and set whatever you want the minimum score for images to be viewable to be,

@techdragon
 
This isn’t for me. I want to make this filter public.

@Xamrin  
Ah. Alright then.

Once I saw -50 in a debate about this. Sometime the downvote galore tag is set very soon in prevision of reaching a high negative score and so a pic who didn’t get that much downvotes can have it. But even in those case, it was added for a reason.
 
The only exception are one or two images making joke of downvotes galore who have a positive score.

I have seen the downvotes galore tag when no one has even downvoted it yet!

When we created the downvotes galore tag in the first place, we agreed on fifty. That was a while ago, so I doubt people remember it.

I’m going with it.
