By now, I'm sure everyone is familiar with the whole Sam Pepper fiasco and how he purposely took advantage of his fans, but not many people know that this happens all-over youtube, and it's not easily stopped.
Seeing as the community of Youtube mostly consists of easily influenced young teens (Ages 11-17) it's not exactly hard to see how this can lead to exploitation, but what is shockingly disgusting is how some youtubers can use their position of popularity and fame to influence their viewers into doing degrading things. It doesn't only occur with hugely popular youtubers either, even small channels with under 50,00 subscribers partake in such vile things (The youtube channel Eddplant comes to mind here)
Now, although the youtube community is actually really great, welcoming and mostly friendly (aside from the trolls) it is definitely home to many predators who constantly abuse any amount of success they receive. This causes controversy between why they are allowed back into the community with 'open arms' when infact they actually aren't, it's just the fact that we have no power over their channel and can't actually force them to close it
Long story short, yes, people can easily influence people for the worst on youtube, but it can also happen anywhere else on the internet, and to be blunt, no, the youtube community does not condone these acts.
