There is a way ive done it myself before.
1. Posting the urls in a blog post
Now with XRUMER report files these urls are in text format, and are not clickable when you paste them into a blog post so are no good for spiders to crawl through, you will first need to convert the text file into html.
Download Easy Text To HTML Converter (freeware) from here
http://www.easyhtools.com/
Run the program add the txt file you want to convert in the input text file box and press the green play button in the top menu; this will take quite a long time dependent on length of url list and may show not responding message dont touch the window at all, just do some browsing for a bit.
2. Copy and pasting urls to blogger
Once the Easy Text To Html tool has finished a webpage will popup with the successful urls drag a blue box from the top to the bottom of the url list with the mouse.
Once a blue box is around every one, press CTRL and C on the keyboard to copy the url list to clipboard.
Create a new blog and create a new post at blogger.com, make sure when you are in the post editing stage you have the tab on compose not html, click inside the box then press CTRL and V on the keyboard to paste the url list into the blog text box, add a title and keywords if you wish and then press publish post.
3. Blog url/rss feed and identi.ca/pingoat method
Copy the url and the rss feed url of the blog page with your url list on and paste both into notepad for use in a moment, goto
http://identi.ca/ set up an account if you havent got one, copy & paste the url of your blog url list into the speech bubble at the top click send, then copy & paste the url of the blog feed into the speech bubble and press send.
Next copy and paste the url of your message page into note pad under the earlier urls(e.g
http://identi.ca/mafiawars/all) and then press rss 2.0 to goto message page feed copy and paste the feed url into notepad.
Now got to pingoat.net type your main keyword as a title; copy and paste your blogs pages url and feed url into the correct boxes and press go pingoat at bottom. Onced finished do the same with the identi.ca page url and feed url, and that folks is it.
You can of cause exchange pingoat with any pinging service you wish i found this one to be convenient.
Also submit the blogs feed url using software like rssbot etc for added link juice.
Addition:
People seem to be worried about putting thousands of links on one blog page, you can use the same method but only post 50 profile urls per blog page per day, so the link building looks more natural.
GOOD LUCK!!
