Do you have any data that shows that trend? I frequently see threads where people complain about how blatant the effect is and how hard they're being brigaded, usually with 300+ karma
One simple experiment is to look at the front page of the subreddit - each link description has, per the rules, the amount of comment karma it has when it was submitted. Look at relatively new posts, and look at the difference in karma at submission time and then as time goes on.
I tried this a few times months ago, and being linked from SRS led to a significant decline in scores on every post in the top 25.

It looks like there's an increase in karma score after it gets linked from SRS
Two things I noticed - all of those comments are more than 12 hours old, which is long enough for the communities the comments came from to counter the downvoting.
It also appears that these are copypasted straight from the front page, you'd have to click through and look at the score on the linked subreddit.
The second part of each line was the comment score/username after I clicked through link, I'll add a timestamp of when I viewed them
(submitted 33 minutes ago by so_srs) "The modern view on gender: Acceptable: Female and spending most of your time on the celphone, reading literotica, and playing candy crush. Unacceptable: Male and spending most of your time on the computer, watching porn, and playing World of Warcraft." [+25] (reddit.com) -> (at 1:16 CST)[–]comosayllama 68 points an hour ago
(submitted 3 hours ago by cakevodka ) things Hitler did were terrible for sure, but, at the same time, it would be intellectually dishonest to not call him a great politician and orator. The fact that he tried to wipe out a couple races and nationalities does not make his achievements in politics and economics any less significant [+66] (reddit.com) -> (1:17 CST) [–]_Pornosonic_ 144 points 7 hours ago
Those combined with the 3 earlier comments I posted make up the last five submissions to /r/shitredditsays(with the exception of one where the original comment was deleted), the first part is the linked comment and the second is the comment score(now with timestamp!)
I can't actually find a single instance from the front page where the score goes down after being submitted. The opposite is usually the case, where the score increases after being posted to SRS
