Yesterday a user submitted a question regarding his draft of a contract. I was able to post an answer before the post could accumulate five VTC. There was only one VTC and the post was closed by a moderator. This is not the first time this happens and I think this question falls under feetwet's presumption of mods being scrupulously open and objective to scrutiny.
Not only was the post closed, but my answer was also deleted. For those who cannot read the contents, the answer at issue is:
This post is hidden. It was deleted 12 hours ago by Dale M.
I added this section to our contract, do you think it is okay?
The section altogether is too repetitive. Although not necessarily wrong, being so repetitive is pointless and renders the whole contract harder or tiresome to assess.
The semantics of the first paragraph is odd. The expression "even though" is misapplied. The purpose of that expression is to avert a conclusion or understanding that typically would follow from the premise that "even though" encompasses. Since the premise "the contractor [...] does not [materially] contribute to the creation of the work" already is consistent with the notion that he would not be entitled to IP rights, there is no need for a rectifying element such as "even though".
If anything, keeping "even though" in that paragraph might enable the counterparty to devise some convoluted argument that defeats your intent. Instead, consider stating that the contractor agrees that neither he is materially contributing to the creation of the work nor would he in any event be entitled to the IP rights.
Which court should be responsible and have jurisdiction over any possible case?
Since the parties are located in different jurisdictions, you might want to specify in the contract which country's/state's laws are to be applied in the event of a dispute as well as the forum & venue where the disputes (if any) would be litigated.
Why was this answer deleted? Where in that answer is the insult, the obscenity, the mockery, or even the lack of substance? The answer clearly addresses the OP's inquiry and contains no elements that would justify deletion. The answer ought to be reinstated.
One can attest from Economy SE, Philosophy SE, Hermeneutics SE, Money SE, Music SE, and many other SE sites, that when a post is closed as "off-topic" the answers that were posted are not deleted. That was the case also on Law SE and this changed.
These answers from posts closed as off-topic or otherwise were not deleted. Please respect the fact that many of us spend thoughtful effort in our contributions.
(The following renders my prior remark of "worse than vandalism" a moot issue and will be of interest to users: I figured out that by typing deleted:yes in the Search field, a user can get the list of that user's contributions which have been deleted, and accordingly ascertain when these were deleted and by whom.)
Arbitrariness and moderation are incompatible.
