While these aren't necessarily adult, this is the list I've used for a while:
Code:
http://rpc.pingomatic.com/
http://api.moreover.com/ping
http://api.my.yahoo.com/rss/ping
http://blogsearch.google.com/ping/RPC2
http://ping.bitacoras.com
http://ping.feedburner.com
http://ping.syndic8.com/xmlrpc.php
http://rpc.blogrolling.com/pinger/
http://rpc.icerocket.com:10080/
http://rpc.technorati.com/rpc/ping
http://rpc.weblogs.com/RPC2
http://topicexchange.com/RPC2
http://www.blogdigger.com/RPC2
http://www.blogoole.com/ping/
http://www.popdex.com/addsite.php
http://www.wasalive.com/ping/
http://www.weblogues.com/RPC/
http://blogping.unidatum.com/RPC2/
now, for another project where I've done a lot more tracking of what works and what doesn't:
Code:
http://rpc.pingomatic.com/
http://blogsearch.google.com/ping/RPC2
http://ping.syndic8.com/xmlrpc.php
http://rpc.blogrolling.com/pinger/
http://rpc.weblogs.com/RPC2
http://www.blogpeople.net/servlet/weblogUpdates
http://xping.pubsub.com/ping/
http://rpc.reader.livedoor.com/ping
I need to merge those two lists and do more testing, but, those are about the most accurate ones I have.
Merged list of the pinglist I've had but refined:
Code:
http://rpc.pingomatic.com/
http://api.moreover.com/ping
http://api.my.yahoo.com/rss/ping
http://blogsearch.google.com/ping/RPC2
http://ping.bitacoras.com
http://ping.feedburner.com
http://ping.syndic8.com/xmlrpc.php
http://rpc.blogrolling.com/pinger/
http://rpc.icerocket.com:10080/
http://rpc.technorati.com/rpc/ping
http://rpc.weblogs.com/RPC2

http://xping.pubsub.com/ping/
http://rpc.reader.livedoor.com/ping
http://ping.weblogalot.com/rpc.php
http://www.bloglines.com/ping
I'm running some testing on the last one, will update this thread later after a quick spot check.
Removing the ones that come back with immediate errors, technorati's server appears to time out so I haven't removed it from the list as part of their network is acting really odd:
Code:
http://blogsearch.google.com/ping/RPC2
http://ping.feedburner.com/
http://ping.syndic8.com/xmlrpc.php
http://rpc.reader.livedoor.com/ping
http://rpc.technorati.com/rpc/ping
http://rpc.weblogs.com/RPC2
http://services.newsgator.com/ngws/xmlrpcping.aspx
http://www.blogpeople.net/servlet/weblogUpdates
http://xping.pubsub.com/ping/
At this point, that list appears to be the most accurate one I've got.
