Blog Website With Keywords Use DNS Static - MikroTik Script RouterOS
How to block sites with static DNS using an automatic script based on selected keywords.

Note:
1. Don't change the rules first, the script, especially for keywords (keywords), preferably the keyword because for example I input seconds and a compass
2. By default, the website that I blog I get used to local ip 127.0.0.1 you can send it to another site, for example for positive internet ip on ip 36.86.63.185
3. For TTL by default for 24 hours (1s), just change it, for example, only 6 hours
4.Please enter the Mikrotik shcedule or via a free script and it is better if the time is running, not too fast, I personally set it for only 10 minutes
5. This script eats up a little of resources so sorry for 750 and below it should take a little longer.
6. I have made a complete description, sorry, my English is a bit messy: p good luck ...

Make sure to only use Mikrotik DNS: 

/ip firewall nat
add action=redirect chain=dstnat comment=DNS dst-port=53 protocol=tcp to-ports=53
add action=redirect chain=dstnat dst-port=53 protocol=udp to-ports=53 
Paste this script on shcedule
