I have no proof, but I find it difficult to believe that /r/gadgets mods spammed every thread for months with raycon earbuds giveaway only for the good of the community and got nothing in return. Raycon, the same brand that pays every other youtuber for advertising their earbuds.

I won’t generalize that all mods were making money from modding, but what is true is that if you have some authority, there is almost always some opportunity for corruption.
