That information is not detailed enough. It shows 41 accounts were suspended or terminated for botting. An unspecified number of RMT accounts were likewise actioned for botting, but were lumped in with all RMT related activity, which presumably includes people who buy gil and such, not just people botting. Finally, it does not address MB botting specifically, which is the only point of contention. As for whether or not it's an increasing problem, if that's the data you want to go with, then...

The trendlines both have a negative slope. Even if I were to clean up the data so that it didn't hold the few weeks where SE did almost nothing, likely due to COVID-19, it's unlikely it would actually have a positive slope. It would likely be flat at best. In the case of the RMT advertising graph, the slope is likely negative due to a spike last fall, but it would still likely be flat even if you excluded that range. Of course the data still isn't detailed enough to tell us if botting itself is a greater or lesser problem, but this is a year of data that shows there isn't a whole lot of change and that, if anything, it has maybe gotten a tad better.
In any case, I've definitely observed and reported gathering bots, but unlike MB bots, you can easily tell if someone is botting (or at least exploiting) while gathering because their character will do stuff that should be impossible, such as cut through terrain. But MB bots? Like there was a guy on Balmung who used to be regularly accused of botting the MB and maybe he did, but whenever I went and competed in his markets, I could easily take them over and shut him out of sales. What kind of bot is less effective than a human at maintaining their MB listings? A useless one not worth not worth breaking down into hysterics over.
Since I'm guessing you haven't even done as much as you told me to do, what exactly is
your evidence? A handful of random data samples not systematically collected combined with your frustration from not being as successful of a seller as you wish?
