If so, the Red Cross, Oxfam and Doctors without Borders should be completely gone from the SERPs. And yet they aren't. There's no way your link campaign is going as fast as their organic one is going now. So I doubt there's such an effect.
There are probably more factors involved than just the speed of link development. The charity sites will have been around for a long time, probably have high PR and backlink count already, and would therefore trigger a lot less suspicion than a site that first went online last week gaining links at a "suspicious" rate.
How new is your site? You might be seeing characteristics of a sandbox, not a speed limit.
I would also think that Google et al. might impose a speed limit but not bust you for it. Instead, they would simply count a fraction of your links. By busting sites, they would destroy genuinely newsworthy new sites that were attracting a lot of attention based on how cool they were.
Well, I guess mine is being affected by the alleged Sandbox filter. But I am not so sure. The website was launched on March 2004. This is when rumors of Sandbox are started. So I guess I am LUCKY person :)
Anyways my website has more than 50 backlinks counted by Google, the HomePage PR is 3 and I had good rankings or better say rankings anyways on Google. <snip>
I have tried to contact Google by sending an email to firstname.lastname@example.org but they told me that the website is not "penalized". But nothing is said about Sandbox which is apparent as it is not officially announced.
I am pretty sure that the site is experiencing such filter as MSN Beta shows the first ranking and on Yahoo I had a No. 11 but currently moved to 150! and off the Google completely!

I think you are in the sandbox(links discounted or ignored for a period of time). I also suffer from the sandbox, for example 6 months ago I added about 50 links from high quality, on-topic, unaffiliated websites and I now rank #1 for allinanchor:formykeyword, yet am ranking 600+ for the keyword search. How long do we have to wait for better ranking? I dont know, IMHO could be a few more months.
It also might be a server problem.
We control a database of a lot of free submit directories. Never had a problem with speed of submission BUT I've always wondered where the upper speed limit is before one gets flagged by SEs.
Likely based around 2 main factors:
1) total number added that week/month
2) the % of new submits compared to existing backlinks
About to submit a brand new site to 400 of them for one way links and see if that raises a flag.
I'll give public feedback (if I remember :-), but I'd appreciate anyone sharing previous work in this area.
