Hi, @HarshKumar, don't worry bro, Moz is good, but it's not Google.
I analyzed your domain name via Moz Pro OSE:
I'm explaining all the 7 spam flags mate:
1. Low MozTrust or MozRank Score: Your website is pretty new I guess, it doesn't have that much of authority yet, so you need to update your blog and get some backlinks, some kind of credibility bro.
2. Large Site with Few Links: Again, backlinks mate... increase your blog's DA score.
3. Thin Content: Moz thinks that your blog doesn't have lengthy detailed content, you can update your blog with good quality and informative articles bro.
4. Small Proportion of Branded Links: Are you generating backlinks via any social bookmarking websites or any other source which doesn't really related to your niche bro? Please avoid that if so.
5. Site Mark-up is Abnormally Small: Looks like you need to change your theme and use a good recent one bro.
6. Low Number of Internal Links: Interlink your posts inside your blog bro, take Wikipedia for inspiration.
7. No Contact Info: This is strange and common bro, don't worry, this spam flag might be fixed in the next update.
So according to Moz, these are the spam flags for the 7/17 score bro. This is pretty common, if you really like the domain name, then you can work hard for a month or so, then check again during the next Moz update.
