: How to avoid domain removal attacks? I see on my website log that someone tried the following URL: GET /domainsigma_removal_xxxxxxxxxxxxxxxx.html HTTP/1.1" 404 188 - "Mozilla/5.0 (compatible; OptimizationCrawler/0.2;

Someone (likely a bot) with the user agent [1] tried to access the resource [2] on your server. Your server responded with status code 404, probably because this resource doesn’t exist.

A simple GET request like this is no reason to assume that an attack is going on.

The bot claims that it’s the bot "DomainOptimaCralwer" from domainoptima.com (this doesn’t have to be true), so if you are curious, you could contact them and ask about it.
