I have to ask: why even trust that IP abuse checking site in you case? The first and second report are basically jokes. Port scanning with the comment "w00tw00t" from anonymous. How trustworthy... Useless report. The second one is a joke because an attempt to access a part of a page is hacking or a web application attack? What. Without proof that the accessed web page was accessed and really hacked or somethow attacked this report is absolutely not trustworthy and also useless. The third report... uhm. Where is the proof? Not even a comment that explains what exactly happened.

What I'm trying to say is that everyone can leave a report and say this IP did this or that... So your AbuseIPDB gets abused to abuse IP addresses. What a useless service.

You better check some real blacklist sites and old reports are nothing when there was/is no repeating of the incidents.
