Someone in Second Life is doing something that makes the whole region run much more slowly than it should.

What can be done about someone using more than their fair share of resources?

[Lexie Linden]

Each region in Second Life has limits on how many prims can be  rezzed, and how many avatars may be present. Other uses of the region's  server capacity include scripts, textures, and sounds.

While there are not explicit rules about how to share these  resources (besides prims and avatars), Residents must not do anything  that intentionally slows the region, nor anything that "hogs" an  unreasonable or disproportionate share of the region's resources. Linden  Lab desires that the Residents of Second Life share all simulator  resources fairly.

Excessively large textures and overly-active  scripts are some common examples of "unfair" resource usage in mainland  regions. In sandbox areas, repetitively rezzing personal homes, as well  as using large numbers of prims for long periods, can be violations. Let Linden Lab know this is happening by filing an abuse report.

Incidents of unfair resource usage are punished as "Disturbing  the Peace"; the first one or two violations result in a warning. If the  disturbance continues, or repeats at later dates, the Resident  responsible can be suspended for three or more days; or (rarely)  eventually permanently banned from Second Life.

On private Estates, the Estate owner and managers are responsible for deciding whether resources are being shared fairly.
