I noticed that out of more than 800 users, at least 100 registered e-mail adresses are not real e-mail adresses, but random fake adresses. It can look like this: email@example.com.
Some users register like this and they are able to vote on topics. I have looked for it, but I can't find a function where every newly registered user must first confirm their e-mail adress before posting a topic or voting.
Any suggestions on how to avoid vote manipulation from uses registering with fake and non-existant e-mail adresses?
