Thank you for taking the time to post this plea. I can explain the reason for the ban. If you talk it over with your child if they understand why they were banned you can reply here to let us know and we can lift the ban early.
Your child was banned for leaving two horses in the free pet farm.
On Famcraft we have a public pet farm. Players are able to claim and protect horses at this farm. Your horses can then be teleported to your home with a simple command.
There are many signs all over the small area where the horses are available that explain how to protect and teleport a horse.
There are also signs reminding players not to leave their protected animals in the farm area. We make it clear that if animals are left at the farm the player who abandons them may be tempbanned.
One of the reasons it is so important that players take their claimed horses home with them is because this free pet farm is based on the use of a spawner which continually produces new horses. This makes it so there are plenty of animals for all the players. When protected horses are left near the spawner area, the spawner ceases to produce horses.
We used to offer free dogs as well, but this same type of protect and abandon issue got so out of hand we had actually had to completely remove the free dogs from the pet farm. We really hope to be able to keep the horses in place as the players really do seem to enjoy the easy access to them.
I hope this explanation helps you understand a bit more about the ban. If you would like to see the area along with the horse protection instructions and warning signs mentioned above, please visit /warp sg, then turn right inside the door. There is a Stargate called "Free Farms". Right click the sign to select the "Pets" option, then press the button and walk in. You will see a door marked "Horses", go through that door and you'll be able to see the horse area.
Again, thank you for taking the time to ask for the details of the ban.
