The site topmeds10.com is a place that owns many domains trying to
direct traffic to them.
They try to look like a search engion when they are not. All links
that you find there they were paid to put there or affiliate links
whare they earn a commissin. Some of them will only take your money
without you getting anything.
It is the owners of sites like that which use the robots to go around
posting messages to forums and sending spam to you. Aviode doing any
business with them, they are no good.
What do they do in trying to get visitors to make money off of?
1) Post mesages (not spam under the law) to any place they find hoping
that Google sees the link before it is deleted. The more links the
more likeley to get into the database.
2) Send spam which slows down the internet and waist your time and
bandwidth. This also slows down the internet to some degree due to the
large numbers of emails.
Yes be worried that Google dues not spider your pages before you
remove the links. They will lower your ranking for linking to a known
site like that one.
