I personally don't really have much to do with the dex myself, but I agree that, as it is now the system can be easily exploited to gain more Rewards, and thereby an unfair advantage over the average player. but the simple fact is that no matter what kinda system we use, this still cannot be avoided. though, if I were to try and fix this problem myself, then I'd probably make it so that when you claim a dex Reward, the System Checks your IP address and block any other attempts at claiming the same dex reward on the same IP, while still using the idea, of having a certain amount of playtime on the server to claim the Dex Reward. this could still be exploited via the use of multiple IP addresses, but it'd at least make it somewhat challenging to exploit the system, but hopefully, this would make it so hard that people would give up on the idea of trying to exploit the dex system. the big issue with this idea is for people who actually live together, under the same IP address, for this issue I don't really have any idea how to fix it automatically, so I suppose that the ingame support chat in the discord would be used for cases like this.
