We have bots on Ragnarok but I can report and wait a few months and they will still be doing it.

So my problem with S-E allowing bots is that it's like saying you must bot if you want to be competitive. The bots basically get a free jump to level cap (fate bots), unlimited company seals, unlimited materials and catalysts and gil (gather bots) with zero human time or effort spent.

Considering the above, it's inefficient to actually play the game, as this takes time and effort to achieve less than what bots are doing since they don't need to take breaks.

I would like to know if Yoshida is actually aware of the scale of the problem on NA and EU worlds. Any kind of comment about this from Yoshida himself would be very appreciated.

The game is still doing ok. While there are a substantial amount of bots, they are a minority, and it hasn't reached a critical state of breaking the game. But if they are never dealt with, it could get worse and reach that point.

I don't expect them to necessarily spend money researching the programs people use and writing detection software to automatically ban people, but at the least it would be great if they could get moderators who will investigate reports and just use their eyes.

Just by looking you can be 100% certain of certain characters cheating, especially ones who use position hacks to jump from node to node. If you can ban these notorious bots who've been doing that for months or years, it will be a much more fair environment and better experience for legitimate players.
