दूरी नही मंज़िल भारी, साथ हो जब मेट्रो हमारी - Mushfique Khalid

Feature request to admin- pls allow users to prevent certain people from commenting on their particular blog. Current only way is to block member which is not good as members gets blocked mutually. I am asking this feature as some people derail topic & make it controversial which ultimately archive the blog. New feature should allow blog owner to disable/prevent certain people posting controversial comments in reply. They will be able to see blog but not reply any further.
Any further suggestions on this is welcome.
