Disallow access from MJ12bot

Disallow access from MJ12bot
Category：Web Server
Pub.date：2019-07-11

There was a sudden increase in access to the site, and the user agent from which it was accessed was as follows

Mozilla/5.0 (compatible; MJ12bot/v1.4.8; http://mj12bot.com/)

I checked the IP address and found that it was from the UK and not dangerous.
There was a lot of access to non-existent pages, and I decided to reject it because it was disturbing.

Deny setting in Nginx

Configure the following settings in nginx

if ($http_user_agent ~* (SemrushBot|AhrefsBot|Linguee|proximic|BLEXBot|GrapeshotCrawler|Mappy|MJ12bot|MegaIndex|bidswitchbot|SMTBot|ltx71|integralads|jet-bot|trendictionbot)) {
    return 403;
}

Other data collection robots are also collectively excluded.
