Ja bih, kao čeznuti kao što je relevantno za moj blog postove, a ne neke mržnje stranice ili porno stranice. Također bih tako dugo dok sadržaj ljudi komentari su relevantni.
Ja bi dopustiti samo jedan link kako bi se izbjeglo spameri, i ja bih držati komentare umjerena sadržaj prije nego što zapravo je objavljena na moj blog.
To je najbolji način da se izbjegne irelevantni komentari i spriječiti povezivanje na loše web susjedstvu.
It is a good idea to let people leave their links in your blog as it gives Google the image that you have an ordinary blog even if you are just having it for the sole purpose of monetizing it. It just looks for natural but I would delete the comments that are clearly spam like "Nike replicas and more www.nikefakes.com". Now making your blog have nofollow on it is a different discussion as then people would probably not post links but I'm not entirely sure if you would get penalized, anywho best of luck!
I definitely would allow people who are commenting on my blog to leave a link in their signatures. I think it is a great way of making commenting a win-win situation. I would, however, alert people to the knowledge that I will delete hate speech, anti-social noise or in-your-face self promotion. Nothing wrong with some subtle promotion though.
