Yeah I've noticed I'm being downvoted again lately, memes and comments. I've been dealing on and off with it pretty much the whole time I've been on here. I think it's because I criticize Trump, and because I'm friends with Jessica. A couple users openly admitted to a concerted effort to troll her and all her friends off. I'm not going anywhere though :-)
Yeah I get it when it's something controversial, or NSFW or something that could rub people the wrong way. But I've even had my innocent comments on my own memes to friends downvoted to low rated at times. It's so bogus the site even allows that
