google shows captchas when you search more than one term on repeat.
if your going threw google saying
"ExploitedScript.php"
"SploitScript.asp"
"ExploitME.php"
etc, it will show a captcha
if your searching
"keyword" "blackhat" "tag"
"keyword2" "blackhat" "tag"
"keyword3" "blackhat" "tag"
it won't.
i do my research before i write my software, or it would be one huge wast of time.
i understand you asking questions, i would too.
Thank you very much for answering the questions. I really appreciate it as opposed to flipping out like most.
