Could it be the whitepaper writer made this plagiarism mistake? Cause sometimes some writers just copy and paste from successful projects. Though I expected they should have run it on copyscape before publishing this on their site.
That's exactly an excuse that these people use, "it was an honest mistake sir, our whitepaper writer copy/pasted by mistake, somwhow huge chunks of someone els'es material ended up in our whitepaper" , or even better one "company we hired to write our whitepaper tricked us, it's their fault and not ours". So no, in cases like this it ain't mistake for sure.
People do plagiarize due few different reasons though; some do it simply because they are ignorant, and for some reason they think that it's perfectly fine to copy parts of texts without proper referencing even if its just some technical part of whitepaper. Majority fall into those that are perfectly aware of what they are doing, but what they are not aware of is the bitcointalk's stance on plagiarism so they end up like this, tagged and flagged.
In some extremely rare cases I could believe that someone made an honest mistake, for example if everything in whitepaper is properly referenced, but for some reason reference or two was forgotten to be included. I have yet to come across such case though, usually it's just a good old fashioned intentional plagiarism.
Unfortunately some investors and bounty hunters will fall for this.
To be honest, majority of bounty hunters couldn't care less whether this is a scam or not. If CryptoSwap.Finance started bounty campaign today, bunch of them would join without thinking twice, even if they saw thread started being tagged for scam.
