I think a very well drafted editing policy for OEIS Wiki would be the
first step for preventing all that. Note that in contrast to
Wikipedia, OEIS _has_ allowed "original research", provided the
sequences have some intrinsic idea, not
just self-promotion.

(However, I remember that there's a restriction of not allowing to use
submitter's name as a part of sequence's name.)

Yes, I don't understand why in Wikipedia they couldn't just briefly
mention it in
the end of entry for Lucas polynomials/Fibonacci polynomials,
that,
"sometimes B_n(X) = U_n(X,1) + 3 * U_{n-2}(X,1)    for n>=2.
are called Boubaker polynomials"
(if there really exists a published paper using that name!)
and then rest the case without continuing delete/recreate-wars.

Or make a whole tables of "Polynomials derived from
Lucas/Chebyshev/whatever polynomials", with myriad of entries with
various surnames.
