Problematic visitors?

Who's Online Displays Spiders?
Display spiders in the online list. Note: This setting only takes effect on the portal and index pages.

Ok they also won't show up anymore :-).
Bye bye crawlers

Is this because they really cannot view the forum now, or because their visits are no longer displayed to us, the users. The whole thing looked a bit troubling to me. This was the first time I actually saw Facebook and Twitter visiting/crawling and possibly scraping websites. They are not search engines.

Do we have any widgets or buttons that connect to those sites? For example, "share" or "like" buttons that uses a Facebook or Twitter login? That could be counted as a way of inviting them to collect data.

But if there is no such thing in place, they may be doing something against the law in some parts of the world. Unethical altogether.
