They -obviously- can see that you have a WH if you aim through walls and stuff.
But if you're asking like "Can they see what I see -(red dots and other stuff on the ennemy)- when they spectate me?", well, I should laugh so hard.
Of course not, they can't.
After this, if you got TEMPbanned, first, you can use a GUID changer (
This one for tekno and
this one for 4D1)
I know it can unban you from the server where you got TEMP (not def) banned on Tekno, but IDK for 4D1
So it will help if moderators don't have right to ban you forever.
Anyway
Also, if you want to be in peace, just learn to not aim people trought wall or even look at them. (If you goal is to make people think you're legit)
Just... IDK, let yourself be killed if you know that your WH will be spotted if you kill the one who is about to kill you.
You can also try to use a name-stealer and take another player's nick, by this way you either will be tempbanned with the other player if you don't change your nick more than once; or they will let you play until one of the two players leave.
