Because you are DT, So I challenge you, prove your accusations, if your accusations are not proven then it is defamation and you should apologize to me and 10 negative tags because you abused your DT power
Because you don't care about signature campaigns
Giving someone a neutral tag is not necessarily abusing DT power. He has not harmed your profile and has likely not hindered you from making money if you did apply to a sig campaign and got accepted. Do I agree with his tag? No, I wouldn't leave 1 like it even if I had the same thoughts about you, but he is him and I am me.
What I bolded is also an incorrect statement. If he didn't care about sig campaigns, he wouldn't be in 1.
