Scary nonsense form submissions

Hi all - I have forms on a number of unrelated web sites that just send me an email for one purpose or another. There are 2 to 6 fields: name, email, comment, etc. No big deal. Recently I've been getting a lot of weird submissions. I'll receive half a dozen at a time, with all the fields filled with some kind of garbage contents. Here is one example from a form on my americansubstandard.com site: ---snip--- COMMENT: ngeiszka@americansubstandard.com NAME: ngeiszka@americansubstandard.com ---/snip--- Other times one of the fields will contain a complete multipart submission, like this: ---snip--- COMMENT: jhynvyf@americansubstandard.com NAME: jhynvyf@americansubstandard.com Content-Type: multipart/mixed; boundary=\"===============1655480186==\" MIME-Version: 1.0 Subject: e8df6b7 To: jhynvyf@americansubstandard.com bcc: jrubin3546@aol.com From: jhynvyf@americansubstandard.com This is a multi-part message in MIME format. --===============1655480186== Content-Type: text/plain; charset=\"us-ascii\" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit xqofli --===============1655480186==-- ---/snip--- I wonder if this is some kind of automated attack attempt. Does anyone recognize this type of thing, and is it potentially dangerous? Should I do something about it? - Brian
