Vitalik will lessen the reward for excavators by 80%.
WTF? Excavators? I get that it's sort of a synonym for "miners", but these types of posts just make me slap my head. My head actually has red palm prints that I don't think are going to go away.
Good catch, OP. Did you catch these manually or are you using some sort of program? Also, did you report these thieves?
They might be using an online Rephraser/Rewording Tool and copying and pasting the product of it. It seems like this amateur mistakes will make them be easily caught of their wrong doings. These kinds of tools are widely available online however all of them don't work 100% as some words are really not meant to be change just like the mistake you pointed out. Although a lot of the words have been changed you cannot consider this as a paraphrased version of the original post as merely changing the words is not enough to make them officially your own words.
