Unfortunately this means for those few months the botters and RMTs have free reign and are only moderately disadvantaged for a short time when those ban waves occur.

The most affected part of the market however is the sale of crystals/shards/clusters, which would likely be prohibitively expensive if it wasn't for those botters to be frank, so it's a double-edged sword.
If SE could be more proactive on the issue, they would also need to address the balance of obtaining crystals and shards in great enough quantities as well.
Every week. They purge every Thursday.
