Dear Erik,
I can not believe that attacks have stopped after including into blacklist.
Wordpress answered me that they have not structure to use htaccess.
Thank you very much!

Dear Erik,
Thank you for your advice but I have not enough experience to fight against hackers.
Could you give me step by step instruction how to ban this IP 91.243.100.70?

Is it possible to check fiction emails by submitting CF7?
Hacker above always create different emails for submissions and I think these are non-existed emails. Maybe just stop fiction emails instead ban ID?

91.243.100.70 – not my IP address.
Thank you very much for website. We found hacker’s name and address. There is another region. Russia is huge country and it is located more than 2000 km away.
Thank again!

Dear Erik,
I installed “WordPress Zero Spam”, changed CF7 (deleted some non-informative rows) but spam continues to arrive. What else I can do?

I have Akismet Anti-Spam that is automatically managed for me via WordPress.
Would you recommend me more effective?

When I entered IP address there I have got the following message:

No registry RDAP server was identified for this domain. Attempting lookup using WHOIS service.

Actually I am in desperate and do not know how to stop above descripted spam. Help me please.

Dear Erik,
I replaced [text* your-name] on [text* name-454546] in my CF7 but spam continues to arrive from the same IP address 91.243.101.52. May I know where this IP address located and stop arriving from this IP?

Dear Erik,
I replace [text* your-name] on [text* 1231231-name] in CF7 but now on page screen appeared just

I have antispam plugin – Akismet.

How can I send you screenshot of my CF7 to check what is wrong?

Dear Erik,
Thank you for your answer.
I always place the asterisk after the tag name file* but hackers could always sent CF7 without attaching file. How was it possible?

I can not use specific names “your-name” “your-email” because I never know who will submit paper.

Also I have some more problem.
After submitting CF7 my customers do not receive confirmation email on “your-email”.
What do I need to fix so that my users get an email to their inbox that their filled CF7 has been successfully received?

In addition in field “your-email” customers sometimes put wrong/false/nonexistent email.
How to avoid filling the nonexistent email in CF7?

Dear Erik,
Unfortunately it does not work because they changed name and sent it as Парикхмахер_boiff <leontev.valeriy111@mail.ru.

How to make the button “Choose file” as required? Then, I suppose it will be no possible to submit CF7 on https://ics.events/journal-of-digital-science/ without attaching the word file.
Is it possible to enter something like this:
<label> Your File (required)
[file* your-file] </label>
Or just add [/file-attachment] at the end of [file* file-945 limit:5000000 filetypes:doc|docx|jpg|jpeg|pdf id:your-file class:file-attachment]?

Is it possible to define an IP address from which these hackers always send me rubbish form without paper for my journal?
All the best,
Dr. Tatiana Antipova,

Dear Takayuki,
Thank you for your response.
I used plugin “Contact Form 7 – PayPal & Stripe Add-on” but now I deactivated it and my issue disappeared (maybe temporary)
Best wishes,
Tatiana.
