[seqfan] Use of Easy keyword

Seqfans,

I keep running across sequences in OEIS with simple 

descriptions or definitions but which, in one way 

or another, depend on factorization of n. The problem 

of factorization is still hard (or intractable) for 

arbitrarily large n, but many of these sequences have 

been given the EASY keyword which seems to be a bit 

misleading. Should this keyword be dropped for such 

sequences?
