On September 16th, after the announcement of the distribution information of the Catizen airdrop, some players were unhappy with the changes to the token distribution model and distribution criteria that were not communicated. Developer Pluto Studio admitted that they did not disclose the changes in the criteria in advance. After the opening of the CATI airdrop interface, several players expressed disappointment on X because they received a lower-than-expected share of rewards. In addition to this, the Catizen team previously stated that the rate at which players earn vKitty in the game will be the main determinant of airdrop allocations. But earlier last Sunday, after revealing airdrop allocations to players, Pluto said it had actually changed the design of airdrops after discovering that some players were using artificial means to increase revenue. It said: "During the review of the data from this CATI airdrop, we found that many bot accounts took advantage of this public rule to try to acquire large amounts of CATI tokens by using scripts to increase their vKitty monetization rate. In this case, following the original airdrop criteria would seriously harm the interests of genuine players and community supporters.
