banline

[Justine Solano]

what are the current rules about banlines ?  (LL stated rules)
Max altitude ?

minimum warning time ?

These are not "rules", simply a statement of how formal ban lines work.

Maximum ban line height for "no entry" or "pay to access" (in other words, "allow public access" is turned off in the parcel options) is the parcel's ground elevation plus 50 meters. If a user is explicitly banned by name, the height is the parcel's ground elevation plus 5000 meters. On current viewers this is visible to the full extent.

There is no such thing as a minimum warning time on ban lines.  They always prevent entry immediately.

If you are thinking about private security systems, that's a different matter.  The only rules there are the ones that are made by the landowner.  On my sim, for example, I specify that residents are not allowed to place ban lines at all or to have private security systems below 300m.  I know of landowners who require that security systems give a 10 second warning.  It's all up to the landowner.
