I think that modern day prophets phenomena died down after the '80s and '90s.
I get what you're saying Azriel but there's no such thing as dying down one of the 5 fold ministry gifts as found in Ephesians 4:11
“It’s he who gave some as apostles others as prophets, others as evangelists still others as pastors and teachers”. About Apostles there are no more of those that give new revelation as the original 12. There are Apostles in a lower level which basically means those who establish works. We might call them missionaries today.
And remember if you make a prophecy and it doesn't come true that makes your false prophet.
That was a standard in the OT. NT prophets don't have the same empowerment to function in the same way OT prophets did. Heb 1:1,2 in times past God spoke through Prophets (exclusively) but now he's spoken to us by his Son. We are now led by the Spirit within us or the inward witness primarily. There are NT prophets but they don't carry the same force as OT ones. But do prophets have to be perfect today or deliver a perfect message? No. 1 Cor 14: 29 even states, if prophets in a place speaks let the others judge....so they seek a consensus to get a feel if it passes the smell test in what they're saying.
Even though I happen to like Hal Lindsey he would be included in that group of false prophets.
People tend to think someone who teaches on end times things that would make them a Prophet. Not necessarily. It can just mean they're teachers teaching an aspect of the Bible. What goes along with a prophet is one having revelation and it can be insights into being a blessing to those around them. But even non prophets can have that too but a prophet experiences it more.
I would be extremely leery of anyone claiming to be a modern-day prophet.
If someone has to announce it
as in they want it to be a title over their life that people go by I'd say they're probably not anyway. It should be revealed as self evident and people know by the fruits coming from their lives that they might could be, be considered to be a prophet.
I attended a Foursquare Pentecostal church as a guest a few times. Different people would stand up and prophesize and then say "Thus saith the Lord". I Just Can't Go For That, not my cup of tea.
That wouldn't make them a Prophet merely because they gave a prophesy. Let me explain one might do work on a car....but that doesn't mean they're a certified mechanic. And one who is a Prophet
or one giving a prophesy doesn't have to deliver such by always saying Thus Says The Lord. They can do that but not always necessarily in fact I find it sometimes more beneficial to not seek to do that at all.
There are times I feel God has told me to tell somebody something. I don't many times go up to the one and say God told me to tell you this....but I go up and say I was mediating today on a scripture that I thought was good and I share it. They look at me in great surprise and say to me, "Oh my gosh.....I needed to hear that today! I feel so encouraged!" I actually knew they did need to hear it for it came to me by revelation but to walk up and say to them Thus Saith The Lord....if you're wrong then you've made yourself look foolish.
Let them say that was God speaking their heart.
