Long-term abuse
This page is not a noticeboard. To report vandalism, use the administrators' vandalism noticeboard.

This page summarises a limited number of long term abusers, to assist members of the community who believe they may have cause to report another incident. Note that this page is not a noticeboard. Names should only be added for the most egregious and well-attested cases. Most users here will have been banned, some on multiple occasions.

Cautionary notes
Don't provide too much info
The text should tread a careful balance between providing useful information and providing enough to obstruct detection. In general such information should only be shared with users of a high level of reputation.
Hints on useful info
Consider providing just a summary of the behaviors and nature of disruption, key case pages (SPI/ANI/RFAR), and the names of current experienced users familiar with the abuser (with their "giveaways", history, behavior traits, etc.)
Don't use LTA unless needed
Only add vandals that have a need to be pointed out, especially ones whose contributions could be confused for good-faith edits by somebody unfamiliar with their modus operandi. This includes sneaky sockpuppeteers, prolific trolls, POV-pushers, editors who add deliberately false or biased information and promotional editors. Blatant vandals whose sockpuppet accounts would be blocked swiftly as vandalism-only even if they weren't evading a previous block usually do not need to be listed here.
Use language carefully
Do not use language that glorifies vandalism. Do not use relative time phrases such as "lately", "recently" without qualification (use "As of date...").

For help, please ask on the project's talk page or contact one of the helpers. If you need more information on an user listed here, your best bet would be to contact the user that submitted the report, which can be found in the page history.
