If you mean the ‘take any quest you want’ that started the whole thing, it’s not a hack (at least not in my book) but rather exploiting a loophole in the coding since it’s using something in the game in the way dev didn’t intend for. (Similar to dragging world raid boss into city in vanilla wow or the paladin one-shotting world boss by stacking up counter attacks)
And I did say to move the actual method to PM to avoid exploiters…get ignored…then exploiters do their thing and crashed channels…
Maybe they were still looking into it then?
After all the link only showed the result, and it’s not until the hotkey thread they we get actual glimpse into the how.
But from that point they have what? 2 days?
On the other hand, things like people typing in color/large text is not something that carpet bomb solution will work.
If you ban those special code, then you’ve just disabled chat emote and item linking (or even party invite tag)
If you ban only specific thing, they can find the stuffs that isn’t banned and still do something. (and the…less-informed crowd will cries “it’s not fixed!” for them)
