Is it possible to cloack a redirected domain?

Hi , i want to give a shot purchasing many domains and let them all redirect to a domain that is my legit offer.However some problems pop up :

-Can i cloack a domain that redirect to my offer’s domain ?So crawlers don’t go to my offer ?

-Or should i cloack the main offer domain and send the crawlers to (for example After they have clicked the non-offer domain ?
