It's probably been suggested before and I really don't want to start a new thread bashing land scanners or the people who use them. Although I do trade land, this suggestion comes mostly from my perspective as a land owner.
First, some observations:
1) Land traders that find public land, generally sell it at below market prices. This is good for everyone. Good for the land trader because they get an easy profit. Good for the residents of the sim because they can buy the land at below market prices.
2) Land that goes to auction usually sells at market or above. I've seen this over and over again, but there's one lot in Atis that is a gross example of this. I was outbid when it went to auction and for the past 2 months this PG lot has mostly been for sale at $10/m2 and remained empty. If this had been released instead and resold by an average land trader, I could have picked it up for $2 or $3/m2 easy.
It just seems to me that the solution to all of this is fairly simple. Instead of having released land broken up into 16m2 squares that are hidden from the land search function, it should remain whole and show up in land search at $1/m2. This would allow land traders to find the land without land scanners or flying around. It would facilitate getting the land to the people who want it and at reasonable prices.
I'd really like to see abandoned land treated this way too. I personally see no value in sending abandoned land to auction. I guess it acts as a $ sink, but it also seems to drive up prices in general and make it more difficult for the people who need the land to get it.
