I think giving an example would be good. Could you please state some of the new announcements that are fake and contain viruses that you've seen? I'm kind of curious too about the poster with high activity and a lot of merit.

PS. Having these would help as well:
* a browser extension like EtherAddressLookup and Metamask (even without an account) for blocking malicious/phishing sites
* an antivirus software which blocks malicious sites and softwares even before/during download
