Everyone has been focusing on the RMT spamming in the large cities but ultimately it's not harming the game; other than being very annoying. But the mass use of a Gathering bots is harming the game. With bot's gathering for +36 hours the amount of mats coming from them into the general economy is large and distorting.

I have seen and reported many of these gathering bots. But it seems that SE just isn't doing anything about it... For instance I reported a bot that was mining in Southern Thanalan on Sunday night and again on Monday morning. As of three hours ago, that bot is still there mining. Over 36 hours later the bot is still there and still mining. They teleport from node to node(often they are stealthed because, why not when you don't actually walk anywhere).

In FFXI SE was aggressive about getting rid of fishing bots, in FFXIV it seem reporting them does nothing.
