Steam has no love from me today. There does seem to be a difference of mods installed by steam. It hints of phoning home. It is hard to call it a game for the family. I’m just saying while listening to real world events. Um… distracted.
I’ve heard of such purges. It was fun. 
This makes it sounds like a smash and grab. Maybe you need at least two bases.
Was affected by this as well pn official PVE - there is a workaround - just make sure you blocked all the entrances with walls or foundations. Like putting wall right behind the door/gate. Spawned enemies won’t touch your base, since they are lloking for “easy” entrances, so blocking those entrances seems to discourage them from attacking at all.
Thank you
As you said blocking all entrance stop those attacks.
But to be honest purge mechanism shouldn’t allow to use purge against other player specially in PVE and PVC. 
As @Teddd said: the only way is to bock off entrances that woud otherwise offer a pass through your base is a solution.
I just want to add, that fences or half-walls do the trick and you can easily jump over them, which does not restrict you own movement in and out your base.
