My best guess is that it was an innocent mistake which I think a good member of the forum agree with. Well, I'll ne waiting to see what others think.
When you copy and paste something, a long paragraph or two then you copy the whole thing and paste it. You do not notice few words in the middle and change anything unless you are intentionally changing it.
I understand that you are a very busy person with many projects you are managing their signature campaigns in the forum plus other personal engagements, which could be the reason you may not have chance to take a look at Dr.Bitcoin_Strange account and post history to see that he has never used anything such as you have suggested neither has he been accused of plagiarism in the past so I don't see why he would want to start now. This a lone is the reason I have the conviction that it is an innocent mistake. There is really no point stressing this since Theymos, in his good judgement, also believe this it is an innocent mistake and have given him a second chance. If Dr.Bitcoin_Strange is a sworn plagiarist or have resorted to plagiarism, then let's watch him because it won't be long before he reveal himself and be caught with undeniable evidence.
