It should not be difficult to find evidence yourself though. Just pick one person who has added lauda to their trust list; there is a ~1 in 9 chance of it being a clearly purchased account, and from there it should not be difficult to find the rest.
The burden of proof is on the accuser. You make a pretty shitty case if you can't provide such, and instead tell people to find it themselves.
There is no burden of proof in the court of public opinion. This is just a smear campaign although I do suspect there may be some small truths to some of it.
Of course there are burdens of proof if you are going to allege something then you need to provide a clear description of what you are alleging, and you have to provide at least some facts and logic to support what it is that you are alleging to be some kind of problem, whether that is breach of rules or morality or law.
huh? Maybe we live in different realties. When I look around I see people making claims, blatantly lying about things but as long as you have enough sheep believing you it becomes the "truth", at least for a certain portion of the population. I did say "smear campaign" did I not? i.e. "a plan to discredit a public figure by making false or dubious accusations". Don't need any proof when that's your plan.
