"Teleport Backdooring (Warning or Game Loss): Teleporting directly
into back of opponents' base or into the forest/trees area of
opponents' base through the use of the Teleport Skill (from Furion)
or Boots of Travel is banned. However, teleporting just
outside opponent's base and walking in (including windwalking or
blinking) is not considered back dooring and is hence
allowed. Base here is defined as the area bordered by
edge structures inside the base at both the Sentinel and Scourge
side. The outer most two towers in each lane are not considered as
border of base. "

"#4 Backdooring. Heroes that can teleport (Furion) and backdoor
will be banned for exploit. This includes teleporting onto the KOTL
ultimate(not just furion, anyone with BOT). All other
heroes may backdoor. To further clarify, you CAN backdoor with
furion / KOTL... what you cannot do is use any type of
teleportation such as teleporting onto KOTL ulti with BOT or using
furion's teleport spell (even with morph) to TP inside the enemies
base. You can teleport near it, like in the forest below it, and
then walk in, that is ok. You simply can't TP directly
inside their base, or right next to a tower in their base etc...
This is not in black in white as to the radius of how far you need
to be to not get banned for TPing into their base, as usual, mods
will have full discretion when deciding, don't be stupid about it.

So if we clearly define backdooring as teleporting into opponent's
base it's not allowed. But what about windwalking to the person's
base? What about an overpowered Sven who solo's towers and
bases?What about furion running in raising treants and teleporting
out of base?
