[ASK] RSS Ping for Indexing ?

Hi,

I'd like to know if this will work for quick indexing bulk backlinks (10k+) :

1. Put all your backlinks into RSS Feeds
2. Ping your RSS feeds to ping service such as pingomatic (not rss submission) to let the spider indexed your rss feeds and hopefully all the backlinks.

What's the drawback of this method ?
Also, is there a max number of links on rss feeds that are allowable (eg: 1k links per rss feeds)?

Thanks
