When you create backlinks, you want them to seem as natural as possible... Some pleople say you shouldn't create more than 50 backlinks each day for a new domain, because it will seem unnatural and google won't like it.

But to be honest, if you post them in different places, it will take time for google to find them anyway, and it will seem more natural. You can essentially post as many as you like if you post them in different, relevant places.

But if you ping them all, it will be a little suspicious to google, and you won't get as many brownie points for it.

Google know how to crawl all the sites that they think are important, so if google can't find the link themselves, then they probably don't care...

It is a good idea to ping your new websites, but backlinks aren't really necessary if they're of high quality.
