Brigading
I know that I somewhat spoke about it in the first post - but I'll go deeper this time - with more examples.
I could speak about how the earlier post was brigaded by SRS and how it went from 87% upvoted to 66% upvoted, but it wouldn't be enough, right?
Here's 3 clears examples of SRS brigading. As you can see, the posts went to the point of losing -96 votes. But it's not just those three post. If you look carefully - it's nearly every post they link.
Here's another post that was +109 when it was posted to SRS. After the brigade it became +13, but now it's sitting at +24
Here's a post that was +16 when posted to SRS. After the brigade it's at -152
Here's a post that was mass brigaded by SRS. It was at +181 at the time of posting. After the brigade, it's currently sitting at -560
Here's a great compilation of 19 instances of SRS brigading by /u/entp.
I decided to go check their front page for evidence. Here's one such example where karma dropped from +80 to 69. It isn't much, but still a brigade...
Here's another clear brigade which got a user's karma drop from +28 to +7, losing 21 karma.
Now many of you might think that it wasn't SRS that downvoted these comments - it could've just been others downvoting a comment they didn't like. However, here's a KIA post which shows that it's when comments get linked on SRS, the downvotes start to come in
Well they're not new to this. They banned submitting np links because they found it 'annoying' and 'pointless'. Here's more proof. That comment went from 20 to -2 points.
Here is a screenshot of a comment when before SRS linked to it: https://i.imgur.com/9zMt7Qj.png
And here it is now
