The problems he had (and frequently - I know because I had to field most of the questions) were things like an Oriental name being written differently in Japanese, Chinese, Korean, old Japanese, old Chinese or wrongly (Rui Naiwei's name is almost always written wrongly). Whenever he met a name that was new to him, he didn't know if it was a new player or just a spelling he hadn't seen. Often he assumed a new player and made an entry accordingly in the database, only to have to unravel it later once he discovered it was an old player. It's easy to imagine the huge amount of work this takes, and why he eventually grew sick of it.
This has absolutely nothing to do with the merits of a numbering system, and everything to do with a lack of language specific knowledge on the part of Ales. Had Ales chosen to use names instead of numbers, the same issue would have cropped up just as often, and with exactly the same outcome.
Everyone and their mother is using numbering systems everywhere. SSNs, bank accounts, license plates, house numbers, zip/postal codes, phone numbers, etc, etc, etc. There is a good reason for that. It is efficient and prevents errors.
