Tolong jelaskan mengenai Blog spam dari Spam (éléktronik) dalam bahasa sunda

In blog spam the targets are weblogs.  In 2003, this type of spam took advantage of the open nature of comments in the blogging software Movable Type by repéatedly placing comments to various blog posts that provided nothing more than a link to the spammer's commercial web site.  These link would in théory enhance the ranking of the target page in séarch engine indexes.
