Establishment of AS61758
Unfortunately, the exact establishment date of AS61758 is not readily available in public AS databases. AS numbers are typically assigned by regional internet registries, and while they keep records of assignments, these records might not be fully accessible to the public or might not include historical assignment dates.
Malicious Use of AS61758
Concerning the question of hackers or spammers using AS61758 with malicious intent, as per the information available on CleanTalk's blacklist database, there doesn't seem to be a significant record of such activities associated with this AS number. However, it should be noted that any network can potentially be abused by malicious actors, and the presence of an IP address in a blacklist could also be a result of a compromised system within the network rather than the intent of the network owner. It's important for network operators to monitor their systems and take action to prevent abuse.
