This method only works within your magazine, and will remove downvotes or upvotes on comments as well as posts.
To implement it, go to Magazine Panel -> Appearance, and enter the following in your CSS box to remove downvotes:
{span style="color:#323232;"}.vote__down { display: none !important; } {/span}
and/or for upvotes:
{span style="color:#323232;"}.vote__up { display: none !important; } {/span}
Example with downvotes removed : @13thFloor
Many thanks to @Anafroj for writing the original CSS code, and suggesting it as a way to combat trolls. Note this test shows that standard CSS works in Kbin, but you do have to replace <> with {} to get it to parse properly.
This isn't a perfect solution, but it should mitigate the amount of users that try to sink communities through downvote spam.
Hi @Pons_Aelius - per my previous comment, the discussion thread is open here if you would like to participate further.
Side note, the two trolls I mentioned that led to this post, @cre0 and @some_guy showed up to prove my point with downvotes - they love to chase me around the Fediverse downvoting posts off the forum (been two weeks now - crazy obsessive compulsive disorder on display). It's actually a two-headed troll, as it appears that the accounts are sockpuppeting each other and downvoting within seconds of each other. Needless to say, I'd like to spare our contributors attention like this.
