It's probably also not very wel known that there can be no more then 256 parcels in a sim.
Offcourse the only time you'll be effected by it is when there are a lot of ad lots in a sim.
Interesting
- potential for ad-plot avoidance
-- and land-griefing.
Going WAY off topic, but since the above sparked the thought

........
Land Contra-Griefing:
How a land baron could avoid ad-cutters destroying a sim (in particular a sim with a Linden road running through it):
Buy a sim at auction with the intention of selling as small plots
Cut into parcels
Reserve a block and cut into 16m not-for-sale plots in a quantity calculated to prevent cutting of the parcels set for sale. i.e. end up with 256 parcels on the sim.
That way, an ad-cutter would not be able to buy a cheapo 512, 1024, 1536 and cut it. They could still have ads, but on a minimum plot size of whatever the baron had cut.
In order to make 16m plots, they would have to buy and join a large number of plots into one, cut out 16s, and then try to sell the larger parcels.
As an indication of the numbers. 256x 16m plots would be 4096 metres.
If the sim is being cut into say 512s and 1024s, then do the maths on the number of 16m not-for-sale plots to bring the count to 256.
What's in it for the baron?
Maybe higher prices for the plots as the chances of ad plots are less. Any ad farms that might be created would be on single plots having a single owner.
The block of 16m plots would still be usable for build or parkland, but a bit of a pain for land settings

The block could be offered to or purchased by a pro-bono group.
Land-griefing (as in a third party having control over what one can do with a plot):
A plot owner with a genuine need to cut something like a 1024 into two 512s would have to go to whoever controlled the 16m plot block for the facility. The block controller would join two of the block plots to free up the sim plot count by 1.
Messy perhaps, but it's a thought.
Land-griefing (as in messing with others):
Someone could buy a 4096 or less in a sim that was cut into a small number of large parcels.
They could cut out enough 16m plots to prevent the other landowners in the sim from sub-dividing their land....
Ouch! Boot on the other foot!
