All this complaining about Guildworks reminds me of FFXIV App and its Radar plugin, which is still working fine to this day. Much like FFXIVApp, Guildworks has been around for a while now and is just now catching attention because of hunts (just like FFXIVApp).

I will be very surprised if SE is able to patch or even bans anyone for using it unless that person is blatantly bragging about it in-game, much like how no one ever gets banned for using ACT unless they start harassing people about their DPS numbers.
