You can verify if a web crawler accessing your server really is PetalBot.
To verify PetalBot as the caller:
1. Run a reverse DNS lookup on the accessing IP address from your logs, using the host command.
2. Verify that the domain name is in aspiegel.com.
3. Run a forward DNS lookup on the domain name retrieved in step 1 using the host command on the retrieved domain name. Verify that it is the same as the original accessing IP address from your logs.
Example:

$ host 114.119.160.240
114.119.160.240.in-addr.arpa domain name pointer petalbot-114-119-160-240.aspiegel.com

$ host petalbot-114-119-160-240.aspiegel.com
petalbot-114-119-160-240.aspiegel.com has address 114.119.160.240

1.6 Why My Website Can Still Be Found in Petal When It Has Been Already Added to robots.txt

It takes time to update data in the search engine index database. Although PetalBot has stopped accessing the pages on your site, it may take several months to clear the page index information that has already been established in the Petal search engine database. Besides, please check if your robots configuration is correct.
