Advertsafe. What's a cheaper/free alternative?

Need a solution to drive off IG spiders for about 50 IG accounts (50 different links). All of the links will redirect to the same 1 domain. I'm thinking blogger sites in a form of a simple pre-lander with a "continue to.." button.
Is it safe enough, though? Can IG's spiders see what's behind the prelander? And, should every prelander be different with slight variations?

Bump, I have the same question. I don't trust advertsafe.net with my traffic. Can an IG bot see what's behind the prelander? Can someone recommend another cloaker?

Same question here! But no one seems to have an answer...

Just test it. Shouldnt cost you more then 5$ and 2 hours of work and you have the anwser in a couple days. Dont rely on peoples anwsers test it yourself

leadcloak (not promoting, just using for some fb ads. working fine for me though) offers smaller (99$ to be exact) plans than justcloakit and advertsafe so i went with LC for testing this time.
Everything is testing. TEST, TEST and TEST.

I've filled NoIPfraud survey form but didn't heard anything back from them.
