Restrict all users with less than X amount of posts to only viewing threads newer than X amount of days?

[CZ Eddie]

Would like to be able to restrict less-known forum users from viewing threads older than X amount of days (like, one year or older).
Would be great if the restriction can be configured for only users with less than X amount of posts (like, you must have more than 100 posts).
Any suggestions on how to manage this?

There is nothing built in which will do that.

It would require a third party add-on/custom development.
