The platforms ease for custom token generation is great but because the general public is stupid they can be easily taken advantage of. For example if you check here
http://www.wavesgo.com/stats.html you will see that there has been a good deal of txs happening on a fake MGO token . Some idiots are giving there money away to a troll somewhere because they are just too stupid to check the token ID. Either way I think there should be a filter for none validated coins on the dex to avoid this problem.
