In the following replay you can CLEARLY SEE that those accounts are controlled by 1 entity! The owner of those 4 accounts apparently has also a bad internet/bad computer, as he was occasionally lagging while doing the multitask. It is also possible that this was a human doing this interactions while multitasking thru ALT+TAB.
I dont know where else I am supposed to make the complaint about this. But if this extends any further, it will completely devastate whatever integrity is left of the game!
To the developers and moderators of this forum - I am aware of the rules of your forums! But I have no idea how otherwise I am supposed to make YOU aware of this issue, other than violating your own rules. The replay will show you 4 man party accounts controlled by one singular entity (be it human, or automated program).
The purpose of the owner is most likely to reach bronze 5, and also sell those accounts. My guess would be that this is an incentive created by your own flawed party system. Since people get to rank up easier with lower ranked players. Which has already ruined the integrity of the ranked games.
This is happening on the EU server.
