Agree with DM, However for new websites it can help for a few backlinks not like 100K being indexed for a domain aged 6 months but a reasonable amount between 50 - 100 in a month being indexed will be fine for a new website for first 3, 4 months. After that let google find and index the backlinks themselves.
P.S. If you have quality backlinks, GoogleBot will be crawling High Authority sites and hight traffic volume sites so they are sure to be indexed automatically.
For my clients, after hosting their site, I submit 3 70 - 80 xml/rss backlink feeds and thats all. other 300 backlinks which i create for them for next 3 months are indexed automatically as all those links are on PR3+ domains and have alexa traffic rank of < 50,000.
Anyways, Do not index ur backlinks for domains older than 6 months you will be safe that way.
