[WikiEN-l] Precedents for sanctioning creative disruption

[Nyenyec N]

I was looking for precedents for sanctioning creative disruption (as
described in [[WP:TROLL]]).
But didn't find any at: [[Wikipedia:Arbitration policy/Precedents]].


What if an editor does the following for a couple of months:
* removing all mesages from their talk page (and all the talk pages of
his user pages)
* creating user subpages about alleged misbehavior of his "enemies",
giving them "hypcorisy awards", accusing them of being members of a
cabal, etc.
* [[WP:POINT]], marking pages, categories for deletion in retaliation
* [[WP:TROLL]] (marking articles of his arch-enemy as stubs en masse,
starting stupid votes on policy changes, being a pain in the neck at
the village pump (but carefully))
* Adding provocative (but not necessarily very rude) comments in
article discussions and edit summaries
* Retaliative voting against anything the people on his hit list support
* Rallying troops on internet forums for a "freedom fight" in
Wikipedia to push a particular POV

So if a user learns to do all this without violating the "hard"
policies like [[WP:NPA]] and [[WP:3RR]] too much, can he go on
forever?

Can anyone point me to the closest precedent to this behavior and what
happened to such creative trolls?

Thanks, nyenyec
