Google search blocked after using tools

Hey all!

I'm kinda stumped here. When I am using programs such as keyword elite, niche inspector, etc. I keep getting a block by Google.

I think this is by IP address as I have cleaned out my cookies, etc. after using those tools, but it isn't helping.

This is affecting my SEO Quake toolbar and PR checkers also.

Any help to keep me from getting the Google block when using these would be appreciated.

I have tried a couple of different proxy servers also, but they aren't working with this problem.

Am I doing something wrong here? I am familiar with site design, etc., but when it comes to IP cloaking and proxies, I am a complete newb.

Thanks in advance!

I believe the cause of this, is the program open multi-threads to do their searching and researching by contacting google server and google see this action as an attack on their servers, e.g. ddos, so they block your IP. When this happen, i just switch my ip since it is dynamic, then every thing is ok again, if your IP is fixed, it won't work. Possible solution is (have not experiment very much with it) - use the Google adword research tool on their site first, usually, they have you input Keyword and the Capcha (weird letters), then they do their processing and gave out the result of your keyword search on the google site. Now, after you done this, you can open your program, keyword elite.... etc., and do your thing, it should not block you now. Because your IP had just been logged with your google onsite keyword research. Try it, I don't think you will get block with this tactic, and report back your results. Another way, if you had an Adword account opened, login with it, and see if this will solve your problem. Hope I can be of help. cheers.
