What do you mean by "re-purchased"? Is this like buying tickets that other users made, reusing tickets or reusing the winning numbers from past winnings instead? If it was the first I don't think that makes sense??? Like just do it on your own lol. 2nd one is not even allowed afaik? Like each ticket is only useable for the period it was registered in from what I know. Redeeming it for a period it wasn't registered in would just lead you to having nothing.

As for the last one, I reckon it's just a bias lol. Like people who hit by using past winning numbers ofc naturally announced it to the world. But those who didn't? Why would they announce it lol. Hence a gap was made between sharing winning stories between not sharing them, so people think that it's always going (or most of the time) win.
