How do I find old blocked numbers on BT?

I seem to have hit my limit of blocked/blacklisted numbers and need to delete some, but it only shows me 20 going back a few months, how do I find the very old numbers to remove?
I'm beginning to wonder if it's worth even adding them on a blacklist since I doubt if any scammer will ring the same number  twice.  
For a matter of interest do you normally answer a suspect number, or answer and immediately hang up, or just let it ring?

Call blocker phone no need to answer .

Neither do i bother with blacklisting numbers on BT call protect any more . Spam calls are mostly faked numbers , changed daily .

Blacklist i t may work by turning it off .

Always answer - like the sport of winding them up!

Getting a call blocking phone might help, although I hate the principle of having to pay for extra hardware, because telecoms & government fail to prevent serious fraudsters making large profits from vulnerable people. I use BT to block international calls which used to be even more numerous.  If I did buy a blocking phone I would need one which would accept a headset socket and I haven't found any yet.
