Ah, you must be relatively new and/or out of the loop. Its almost common knowledge at this point certain groups get several weeks of heads up of upcoming changes. People knew the calibration charge change was coming, that 100% bots were not coming back, etc. You can't really post evidence as that generally ends up with a ban on your account. Its out there though. People had weeks ahead of the official announcement to get time off, set up scanning schedules, move large amounts, 100+, scanners out to the area a day or two in advance, buy out the scanner market. There are a ton of red flags on their own with almost every patch that by themselves might make you think that something weird was happening, but when it happens every time, well, when there is smoke, there is likely fire in this case.
