Well I don't know you love BlogSpot or you hate it. But when you use it both can happen. We try to use it for back-links, as landing pages, affiliate sites etc and Google want to keep it clean. Googles Blogger Anti-spam bot is a terrible one which seems have its own mind than set of rules defined by Google programmers. But if you can get pass the bot or stay under radar then you have less trouble. Here are some important facts.

02) Google index Blogger posts faster even without a sitemap or anything.
03) Rank better in Google than most of other web 2.0 properties.
04) You can use custom domain if you want.
05) You can use custom theme if you want.

etc
What you need to do stay one step ahead of anti-spam bot is,
First week make only 2-3 posts not more than 600 words per post and no out bound links. Add a image (better royalty free) and Youtube Video.
Important thing is Publish only after you are done with the post. Till then use "preview" Button. Editing and publishing posts way too often is one way to attract the anti-spam bot.
Good content always work long term. Blogger auto connect blogs to Webmaster tools. There goto site maps and add atom.xml which will get your posts index even faster.
If you use Amazon don't add more than 2 links and keep links noFollow.
Keep total Link count at 3 per post just to stay in safe side.
Inter link your blog posts. This works very well.
If you do link building for these wait for week or so don't start when the blog is too knew.
These facts will help you to keep your blogspot blogs safe and long running.
