How To Check Donor Sites For Filters And Malware

Why checking site donors is important
Any sanction leaves its trace on the site's history and reputation. In the case of banning, significant work must be done to deal with it and get the site unblocked. Promoting the sanctioned site is quite complicated as Google applies a Penguin filter for using the wrong links.
A virus is a malicious code, a result of hacking. The virus can harm the site itself as well as the whole hosting. The latter will cause the spreading of the malware among all the hosted websites. While entering the infected site, a user gets a notification that this is unsafe.
Checking a donor site for sanctions
You may use some link markets' stats that estimate the site's trustworthiness and rank its possibility of being sanctioned.
An analyzer that can help to see the risk of becoming filtered is Websites Penalty Indicator. The tool is free and available without registration. It helps to trace how Google algorithms' updates influence the site.

Doorways create additional sites inside yours that post ads. Proxy and botnets waste your site resources on spam traffic.
Iframe is a severe threat not only for the site but for a computer as well. It can steal confidential information, provide fraud schemes, load trojan, and other kinds of viruses.
Shell gets integrated into a remote server and changes the initial code. Then you lose site control. If the site which refers to you has at least one of the mentioned viruses, this seriously threatens your web-resource.
