Just thought I'd put my two cents in, whether it's wanted or not. OP is clearly misunderstanding as he thinks Snivy (just using him as an example), got a shit load of +1's just because his video was hilarious. Sure, in Snivy's case, it made me laugh for like a minute straight. However, when you look at excessive +1's, or even massive -1's for that matter, you can clearly see it's more of - as Peetah stated - a
bandwagon effect. If you don't already know what the bandwagon effect is, google it.
Usually what happens is that people view a thread and see
certain people +1/-1'ing it and responding on how funny/stupid the post(s) is(are), and then make it into a
trend to +1/-1 the OP (or a certain post), or even in some cases, every post in the thread. Now don't get me wrong, I'm not saying +1/-1'ing any post ever is jumping on a bandwagon. What I am saying though, is that you should be on the lookout for random posts that just happen to be +1'd by the same people who usually do tend to easily jump on bandwagons (not going to give names) and you'll see what I mean.
