We're as upset about it as y'all are and we've been talking about these types of cases internally.
While we've fixed erroneous seeding of people who played normal games moving forward, we can't retroactively fix the cases of people who played their first games a month ago before we pushed the fix. (we looked into it, but it can't be done at the scale or speed that we need it to 😭😭)
The second set of cases look like bots 😭. If a player plays just aram or bot games they don't go through our seeding pipeline. This is also not something we're happy with and are looking at improving, but for these cases in particular, hoping that vanguard removes them from the ecosystem entirely.
Again, apologize for the experience, we're working on things and split 2 reset should hopefully put the erroneously placed players back in their right places.
