The Wreck list is mostly occupied by obvious wreckage.
My guess is that the extra grumpy setting includes the following rules.
If the first comment is a hidden Tip Jar the account is unlikely to recover.
If the first comments are getting zeroes the twelfth comment is the last.
The spambots are harmless at the current level. The new rule is that TUs have five unrecyclable donuts per day and one per donee. I haven't run out recently and am happy to toss one at each spambot to the limit of four. Only two donuts are needed to hide an unrecced comment. As general rules go, this one is working.
