agree, easiest way to change ip and everyone knew about that.

For starters, this my post wasn't created to just accuse these people, namely to discuss the situation, as I am not entirely confident in the decision. In my experience, I am right and these people are really so much silly that used the same address for multiple accounts, at the same time I had the experience when by mistake the addresses were changed by someone with access to the table (maybe even me in part and issue was quickly solved via changes history checking). Operating with such a large amount of data, you can make mistakes, but this case does not look like my mistake. Today I spent the whole day checking out the ferrum campaign and now I'm a little tired and my mind is clouded, tomorrow after waking up I'll recheck everything, because Google spreadsheet allows you to see absolutely all the changes from the creation. After that I will once again read the advices of the people here and the arguments of the "accused". If the error is really mine, I will apologize and return the rewards to the table. I also want to note that the project team is aware of the situation, I do nothing without the knowledge of my customers.
