It is a loss that you withdraw from the contests @votum, because you are a great contributor to the sports platform dwe Steemit. Something like that happened to me and I put flags to all the posts of a week. justifying that I asked users for votes to participate and I was profiting. But I contacted @steemcleaners and they told me to remove the user request for votes to participate.
Of course, that week of post that they put flags, they never took it off, but the next contests I've done have not put more flags.
Thanks for the information. My contests have never required upvotes and each post informs that a comment is all that is required to receive rewards. I have contacted @spaminator but received no response so far. I'm not sure if they are related to @steemcleaners.
