stewaris
MerylStreep this device is the only access to the internet I have and I access all sites incognito, check all cookies and clear them out regularly. I also have an ad blocker and subscribe to internet protection. As well as that, my nephew works in IT and runs scans on all the family's laptops etc on a regular basis. This is one of the very few sites I access on a regular basis and the only one I occasionally post on.
MerylStreep is correct. AI isn't a virus. There are a number of legitimate AI sites which no virus checker or adblocker would identify.
One of them is called chatgpt. I could, for example, log on to it and instruct it to write a post in the style of stewaris on Gransnet. It would analyse any posts you've written in the past and produce a Gransnet-style message. If I wanted to be malicious I could sign up with a username almost identical to yours and post my message and nobody, except you, would realise that you hadn't posted it.
