This blog – like most blogs, I assume – is constantly under attack by spammers posting comments to my posts.
These comments are deleted regularly, but it is impossible to guarantee that the blog will be 100% spam-free at all times.
Such spam will normally be obvious – it will have nothing to do with the post and generally be offering “news” about a pharmaceutical. Often, there will be no links in the post itself – the only clickable item in the post will be the user name.
Do not click such links! They often lead to web pages with self-loading trojans, worms, viruses and other ‘Net Nastiness.
