How to block custom bots on Plesk server?
It is possible to add the required bots into Fail2ban "apache-badbot" jail:
Go to Tools & Settings > IP Address Banning (Fail2Ban) > Jails and click on Manage Filters
Add the required custom bots in the "badbotscustom" value separated by a pipe, e.g.:
badbotscustom = SputnikBot|omgili|socialmediascanner|Jooblebot|SeznamBot|Scrapy|CCBot|linkfluence|veoozbot|Leikibot
