Weird spam......?

Question

Fight against spam

I've been getting weird spam comments on my site lately. All messages are similar. For example, the title is “expensive saunas of Moscow”, and in the body of the message something like “Thank you for the site, a very useful resource.” And that's it. No links, no contact information. And there are many such comments.
The messages themselves are simply cut off by the written anti-spam, so there are no problems with clogging the site. But the question still arises: for what purpose are these creations used? After all, the sense of them in the case of publication is zero.

Answer 1

Maybe the crooked hands of the sender, who forgot to add a link to the resource, are to blame for everything?

Answer 2

to google

Answer 3

I use WP and it has such a feature - Before the comment appears: The author must have previously approved comments ... That is, if he commented on the article for the first time and you approved his comment, then the next time the spammer can freely leave spam comments.

Answer 4

these are spammer trainees taking an exam))

Answer 5

I recommend trying keycaptcha - an unconventional type of captcha, where instead of entering letters, you need to assemble a small puzzle. users are not stressful, but they completely got rid of spam bots. before that, many people made their way through alphanumeric captchas, they had to encrypt.
and here they even offered to make money on captchas. although I have never seen a paid captcha. probably the project is still at the stage of recruiting clients

Answer 6

Have you looked at the html of these comments? Sometimes one-pixel images with links or invisible blocks are shoved.

Answer 7

Do you need to register before posting comments? Maybe in the profile in the "site" column they put the site? Quite a way.

Answer 8

These are the most primitive spambots that try to send a request using any form they find on the site. The fact that there is no link to the site itself is most likely due to the fact that it is cut out by the parser at the form processing stage.

Answer 9

links are cut by your engine
, they serve to get traffic

Answer 10

I also recently had a similar one on the site :)
The comments are of the same type, like “Please teach the rest of these itnerent hooligans how to write and research!” However, as they suddenly appeared, just as suddenly they disappeared.

Answer 11

I have similar comments instantly appear on the blog when the information is updated.
I have a feeling that in this way spammers are trying to spoil the "content rating" in search engines (duplicates, uncoherent text, errors, etc.), that is, to make the page garbage.
