Yes, I'm afraid you are very correct.

There are two random-upvote filters. This one that does look at higher reps, but have not used the #nobidbot tag. You can only received this vote once a month at most.

Then the main upvoter which does not use any matrix other than they used the #nobidbot tag and it is not NSFW. This occurs as long as the bot has at least 75% VP.

I am looking at creating an organic trending list and also a curated list from the #nobidbot tag.

Got to go for the night, thanks again for the support!
