Currently users need to solve a captcha every time they insert or edit a weblink in the wiki, unless the website has been added to a small white list of “good” sites by an administrator before.
I’ve easily solved several hundreds of them already and imo they are very annoying when doing small improvements to wiki pages. I don’t see the point to require this for users who have already made more than, say, 10 edits in the wiki. Spammers tend to get kicked out before they manage to reach that number of edits anyway.
And while I don’t know whether oour “bueraucrats” would be willing to do so, MediaWiki itself would afaik make it possible to enable such a policy.
The suggestion had been discussed previously, but the discussion was sidetracked in favour of the whitelist mechanism for urls. Feel free to express your support or add new ideas or suggestions to the discussion.
