I've seen a number of issues with Skychat. -Reaching the two-win streak limit results in a 30-minute cooldown before you may win again. If you simply rejoin, the cooldown is removed. -The cooldown only applies if no one else wins after you. If someone wins, the cooldown is lifted. -You can win on different accounts using the same IP address. -If your inventory is full, you simply do not receive the grass prize. It is not dropped, put in your EC, put in /cr claim or your left hand/empty armor slots. With this being said, I do not see what is stopping Skychat from being abused.
Losing items from a full inventory also happens when you win a kit from a crate. I've made a few posts about it but it might be an intended feature and probably won't be fixed. As for the cooldown, it could definitely use an update. If you win 2 reactions in a row, and no one wins the one after, you will still have the cooldown until someone wins, even if no one gets the word in the next few reactions. I think that the cooldown should be 10 minutes in order to give someone a chance to win. If no one wins the reaction after the 2 you won, then you can be eligible for the reaction after that.
Bug reports go in this forum https://skyblock.net/forums/bug-reports.317/ Staff typically don't want abusable bugs being public information.
I have known some high-ranking players abusing this bug - the same players have abused loopholes in the rules to achieve unreachably high baltop balances. I say the sooner this is bought to the public attention as this thread is doing, the better!
