Okay Dhruv, you need to pick your next words rather carefully and spend considerable time thinking about them before posting. I expect only one more post here, repeated posts are not a good look as well as not needed if you spend the time considering your words. I have taken the time to look over your supposed claim that you did not mine all those blocks, I find your rebuttal to be false, you did mine 133 ancient debris within the 24 hour period! Additionally, to this you have mind a total of 309 ancient debris within the last 20 days. This goes against your claim that you have 'never' mined that many ancient debris.
Secondly this gets the post of how you got to such ores, this is an area which you have yet to explain at all. I have spent time looking at over 30 different veins and how you got to them, you mined straight to them. This additionally debunks your claim that you and another player had a 'mining' challenge'. So to me this looks like you are lying to us, we do not appreciate that at all. This needs an explanation, without that anything you are going to say will be called into question and investigated, so no more false statements.
Lastly, you have been caught using x-ray before. You claim of not having any modifications installed which allow x-ray can easily be faked, so is irrelevant. As I have said in the beginning take the time to reply as best as you can as you will only have one chance to do so, give us the truth.
