Looks like you're pretty new here, assuming this is your only account. You might not be familiar with how cynical and jaded people are, and how intolerant some members can be of posts like the one you made. Some just don't want posts like that in their selling threads, but I agree, what you wrote was innocuous.
The threat of negging you for that post isn't appropriate, especially nowadays when Theymos doesn't want red trust being given for reasons like that. I don't know what to tell you other than you picked the wrong thread to voice your opinion in, and not all members are like that. On the other hand, you have to understand that a
lot of newbies just post in order to gain activity and/or get paid through signature campaigns. You're not using your signature space for advertising, so I can only guess that Reynaldo thought you were just firing off a shitpost in his thread.
Anyway, just roll with it; some people are going to react like that, and there's not much you can do about it.
Edit:
your trolling of a sale thread is not cool either. Move on.
Eh, I don't think he was trolling. Looks like he just wanted to share his experience with a keyboard--like you'd do on a normal forum with real human beings instead of shitposting gorillabots. Reynaldo definitely overreacted.
