If you check yahoo's (for example) profile page and click on "Show the last topics started by this person." you will easily see a list of all the (topics) campaigns he opened. Almost as a rule, in each of these threads, there are all contact channels from the project and campaign owners.
I'm surprised if you asked this seriously.
Yes, I asked it seriously, the joke part was the part that said I might get an urge to send PMs. Being so easy, I guess if I had wanted to send PMs I would have had no trouble finding the addresses.
Simply checking the company contacts one can easily get it. For example one can simply PM
winz.io on their forum profile or can join
their telegram channel and ask for admin's telegram's ID and PM them.
How will it be so difficult these days?
Yes, now that I see it, it is very easy. Think I have Telegram but I don't think I've even exchanged 10 messages through the app. So when I see something related to Telegram, I think don't even notice, but I guess I'll pay more attention from now on.
Are you the troll again? If you want us to believe that the address is yours sign a message, but they are two different things, that the address is yours and the opinion most of us have of you.
