I confident I will be removed from the signature campaign and may be blacklisted
That is for the campaign manager to decide as it is within his rights to do so in
his campaigns.
or might get a negative trust after this topic
If you believe someone is a scammer, or someone is likely to scam, that deserves negative feedback. Please provide evidence
This post doesn't make you a scammer, neither does it mean you are likely to scam, so no.
As far as what Royse did goes, we all have our limits, and prolly to him he didn't cross the line, but to you he did. I don't think what he did is cool because some users might turn down opportunities that day because they thought they stood a chance at getting in the campaign, and one user said so in that thread:
Especially when I receive an offer and decline it to then discover it was a joke :/
But overall, and despite those who were affected negatively by the joke, Royse already apologised:
If anyone felt hurt then please accept my apology.
...
Sorry, for any inconvenience that happened to anyone by the prank.
Thus i think it is best to forgive, forget, move on and don't forget to put on your thick skins as you scroll around Bitcointalk.
