hi experts
i log into my web site errors and any things. in my logs there is some referral links or request from russian websites ( with respect for Russians and all people ) that when i check these web sites ,there isn't any link or request to my site.
also i got this error in my log from a russian site:
A parameter named 'p__linq__0' already exists in the parameter collection. Parameter names must be unique in the parameter collection. Parameter name: parameter

what is this? are they hacking my web site?
thanks in advance

Block their IP Address ranges in your firewall.

This probably has nothing to do with any hacking attempt of some sort.
It seems to be a well know bug in Entity Framework (described here[^] for example, but you can find numerous of them if you just search for "A parameter named 'p__linq__0' already exists in the parameter collection" in any search engine).
