I wonder if the link is save. Can we get hacked by just following a link in webbrowser?
Yes, you can get hacked by clicking on a malicious link or malware.
Some can be used to steal your personal information or to bug your computer. You can also get to a phishing link, which is a copy of an original address.
If you're unsure whether or not a link is safe, then do not click on it, and do not spread it.
