How to get rid of persistent bot/hack users?

[Kyana]

I'm sure most players have a bunch of RMT and bot users on their blacklist.
I'm also sure most of these players were reported through the ingame support function.
But many of them still play the game like nothing happened.

My question is, what can we do to get rid of them?
I have a number of bots on my blacklist that were reported for teleporting, speed hack, gathering hacks and so on.
All of them were reported but none of them were deleted. In fact, I just saw one of them some days ago happily crafting in Gridania and it made me really mad.

Since we aren't allowed to name such players I won't do that, but what can I do to get the attention on them?
I can't and won't follow them around all day and check if or when they bot again.
I don't remember the day when I reported them while they were using their bots/hacks.

Is there a way to check the report messages you sent to SE to send them the information again?
Can I just report them again for using a bot "a few weeks ago"?

It infuriates me to see bot/hack users getting to the same level as me in a matter of days or weeks instead of months and then continuing to mess up the ingame economy.
I want them to get the punishment they deserve, but I don't know how.
