OP also forgot about another reason which is already common for all of us, and that is no other than plagiarism. From copying someone else’s content and images without permission or giving credit source, whitepaper and other stuff, you’ll get a red tag for sure. This is definitely a no-no, not just here on Bitcointalk but also in all aspects of life.
I do not understand your accusation, above I have clearly explained, this topic I took with the approval of the original owner.
cheezcarls, not accusing you of plagiarism about this thread but he's just saying that there is another reason why someone gets a negative tag and it's because of plagiarism either from whitepapers or certain websites that you might list. Please reread what he means, he's not accusing you.
Besides plagiarism, there are several other reasons that can also make users get negative tags, namely trolling. Yes, trolling is one of those things forum users shouldn't do if they don't want to get negative tags.
