I'm not sure why you made "10 players" and "recently" bold in my post. I'm pretty sure there are more than 10 players that find a shiny every week. Just because you heard of 10 players within a month there doesn't have to be a change in rate. Imagine throwing a coin. Just because within 50 throws you have a couple rows of 5+ heads doesn't mean the coin was rigged, especially if you only pay attention after you already got 4 times heads in a row.
