Anyone else notice an influx of chinese spammers lately? They keep going to my site and filling out my contact form and sending me various URLs exactly what benefit do they get out of this? Like im going to visit the site and buy something. I keep banning IP's but they change them all of the time and some even seem to be in USA so maybe they are using a VPN. Its one thing to spam a blog where they put up URLS for backlinks but this just goes to my email and it isnt picked up by email spam filter since its coming from my contact form.
I had got same problem but i removed contact forum and put the email address or phone no for contact on my site and closed the comment service on the blog.
Captcha algorithms simply don't work anymore. Some brilliant spammers managed to break this. There is nothing else other than making the contact form ajaxified left right now from my perspective.
