Someone could probably view the network traffic and compare that against network traffic when the blacklist is not enabled and use the difference to determine alts. More time consuming and possibly not as 100% as the existing stuff, but still possible. We also don't know the performance impact of all traffic having to be ran through that kind of filter. I'd like to say it wouldn't be much but this game and network perf ... Well, who knows
100% this. You're still communicating character ABC is the alt of someone on your blacklist, either through a isBlocked flag or through omission of that character. The only difference is you're now performing an additional N^N logical checks every 100ms.
