Help us Stop Spam

Well, we are not going to stop spam unless we make Wikipedia read-only... and even then we have loots of old spam in obscure articles to clean up.

But we need to apply our Wikipedia:Notability guidelines, and we cannot let every link into Wikipedia, it is not a web directory.

Every day, non-notable articles are added to Wikipedia. Many are not even reachable and fail basic quality checks. Companies as well as bloggers and academics try to promote their products by dropping links and references in Wikipedia. Someone needs to clean up, and this is my purpose. I am one of the poor Wikipedia cleaning ladies that have to undo all the link spam people drop into articles that would slowly rot the quality away. WP:NOTEVERYTHING belongs into Wikipedia, it is not a trash bin, but needs to be frequently cleaned up.

While commercial spam has decreased since we require Wikipedia:Paid-contribution disclosure, we still see a lot of non-business spam, such as WP:SELFCITEs, which tend to put WP:UNDUE weight on individual papers, blogs, personal pet projects, and opinions. Please, leave it to others (without your encouragement) to write about your work once it has become widely known.
