[Question] Cloning My Gaming Blogger Site (Same Template & Content) Across 5 Domains – Am I Asking for a Ban?

I need some straight advice from anyone who has scaled blogs on the Blogger platform.

I run a gaming niche blog and currently have 5 different domain names pointing to separate Blogger accounts. My original plan was to speed things up by using the exact same template design and duplicating the exact same content across all 5 domains—essentially creating 5 identical mirrors of the same site.

Before I pull the trigger, I have two major concerns:

1. Blogger Platform Risk: Will Google/Blogger suspend my individual blogs or terminate my entire Google account for doing this? Is this a hard violation of their TOS that triggers an instant ban?
2. Google Search Risk: I know duplicate content isn't an automatic "penalty," but will Google simply de-index 4 of them and only show 1 in the SERPs? Or will it flag my main account and hurt my overall visibility?

Has anyone here actually tried running multiple identical Blogger clones? Is there any "safe" way to do this (e.g., using canonical tags, spinning the content slightly, or leveraging subdomains), or is this just a massive waste of time that will get me banned immediately?

I'm open to any workarounds or harsh realities. Let me know your experiences!

Thanks in advance.

If the content is identical, why not just redirect the extra domains to the main site?

Duplicate content in itself isn't really n issue, but search engines will pick one site and ignore the rest.

If you need five sites, give each one a unique reason to exist, so your effort isn't wasted.

From my experience, running 5 identical Blogger sites is very unlikely to give you any real SEO advantage. In most cases Google will just pick one version to rank and ignore or devalue the rest, so you end up splitting signals instead of scaling.
