Scambaiting techniques?

I haven’t scambaited in a while and I want to start again but I don’t know what should I use for my bait. I’ve baited with real malware like WannaCry and Malcolm’s anti-scam tool in the past but I want to try another technique. Does anyone have good baits or techniques?

@iCy#22372 I like to call them a lot of times for blocking their number and stopping them. If you do that they’ll hung up to everyone.

Pretend to be very dumb. Act like you don’t know much about technology. Have the scammer need to explain everything. And play some annoying audio in a second desktop so that the scammer will be wondering where the sound is coming from.

Waste their time by saying "I need to go to the bathroom" and make some sounds like peeing and pooping that may make the scammer laugh.
