As you know, we have been plagued with the Forum Account Reproduction Movement
constantly. For as long as I have been on the forum, this was one lucrative part that shady users couldn't dodge.
Question: How do we proactively suppress account farming and spammers?
Answer: Reporting posts.
Reminder for those that have forgotten: activity requires at least one post per 2-week period in order to gain the potential (and subsequently true) activity. Erase all those posts... and poof, you've used maybe 5% of the amount of time that they have to rubberband them back to 0 for that period.
If the post is not deleted... then that's good: the goal is to clear spam and disincentivize low-effort posts. If the end-result is achieved without restitution then we should be happy.

To note, even before using any page-wide report buttons (i.e. reporting every single of the 20 replies) it takes me about 30 seconds to go through a page of one-liners. That's usually equal to at least a week or two of time. And if they create a single one-liner, it's likely they'll have many many more.
Most of the offenders tend to stick to the low-hanging fruit type of threads and boards. These include: Trading/Bitcoin Discussion, Economics, Altcoin Discussion, etc. (you all know where)
Take the reins and rear the forum away from spam.
Addendum.
Question: How to we more effectively suppress account farming?
Answer: Delegate some work to combat it directly, using tools that have been available in the past (take a look at rizzlarolla's history)
This is a more top-down solution.
