We seem to have a few people who have brought with them "bad habits" of crossposting the same url 2 and 3 times to different subs within the same 60 seconds. Right now, they're doing it for "karma" without stopping to realize that the important stat is CCP.
While I understand that this is merely an annoyance at this point, if we get even a full-on 1% of users doing this, we're going to see literally the same shit over and over with legitimate content being pushed down and, if the activity is high enough, past the "Next Page" page limit.
In other words, this can be abused by a small group of people to spam the site.
Edit: let me add that you can only hit “Next page” until you hit page 20. Identical posts at the same time eats up slots in those pages. The crosspost itself isn’t a problem. Crossposting at the same time, however, is. Edit Edit: See this thread as for why this is a bad thing: https://voat.co/v/ideasforvoat/2294802/11383193/10#11383193
