You're making a really big deal about a neutral tag as if it's the end of the world. I get it, you don't wanna be wrongly accused of something. If it were a negative tag I would raise all sorts of hell, but it's a neutral and 99% of the time it isn't going to harm you. Not sure why it did this time, but that's the managers call.
I am being suspected even though I have made no mistakes
What do you mean by this? I don't want to accuse you and cause you more drama, but what do you mean by mistakes?
A normal newbie wouldn't come on the forum and join a contest in the 1st week, they would be too nervous to try. Least that's how I feel as most aren't just ready to dive in head 1st. It could happen though and it's not illegal, just odd. You appear to be more knowledgeable than most newbies so of course people might question you. What if you are ban evading and it's found out? Not saying you are, but IMO it would be better if you just shake off the neutral tag and don't worry about it.
50 people could neutral tag me right now and I could care less. Go through my trust history and look at how many morons have red tagged me because they got caught scamming or didn't like my opinion. No, they're not in DT but my point is people can tag you at any point. It's not red so
get thicker skin. You'll sleep better at night.
