Our forum is receiving a large number of forum search requests from 66.249.73.* (apparently GoogleBot) every 1-2 seconds, for example:

This appears to be foreign. The above search decoded is:

김해출장외국인[카톡:+M+o46]{Mss41.c０M}콜걸만남콜걸출장안마Y♐◊2019-02-10-23-53김해☶AIJ☚+출장샵예약출장샵안내콜걸만남♂출장시↼흥출장안마⇄김해

Translated, this is:

Gimhae Foreigners [K Talk: + M + o46] {Mss41.c0M} Call Girl Meet Call Girl ↼Heaven business massage ⇄Gimhae

 

It appears we are being targeted via a spammer, strangely via GoogleBot. I assume the spammers are issuing these searches via Google somehow, in an attempt to get those searches on our forum indexed, so they appear on Google.

Does anyone know how to prevent this? It is causing big performance problems, and we obviously do not want to block GoogleBot from our forum.

you can block the IP range.... enter it exactly as you entered it above.

It's not Googlebot, they are spoofing the name so that you think it is Googlebot.
