Important remarks.

A remark which was or still it is hidden somewhere in OEIS web pages 
promizes to contributors that they might become immortal if
sending sequences to EIS...
Already in the last century I realized: I am not immortal, but I 
continued sending sequences.

If this remark would be replaced  with
the opposite, perhaps the incoming sequence tide would remain
invariant. No number-theoretical contraception or tranquillizers
could stop sequence production of the World.
---------
As t Conwaz remarks...
Concerning quality: no single person (njas) is able to correct and 
filter elder and recent sequences. A commando is required to
do this.
My minimal program will be as follows: 
whenever I send a new sequence I 
force myself to correct some other one of my previous ones and a
randomly chosen from somebody else. This 
method as a punishment includes two good effect:
- may inhibit my submission intensity
- corrects some mistakes 
---------
Concerning relevancy: this is a subjective and more delicate issue
Thus sometimes difference in one term is very interesting...

Example: sequence = {3*prime numbers other then 3}={6,15,21,39,...}
is a trivial sequence.
But: the same sequence together with 175 gives a new sequence of x
numbers satisfying the following relation:

   2Phi(x)-Sigma(x)+8 =0 or 2Phi[x]=Sigma[x]+8

Phi=EulerPhi,Sigma=sum of all divisors

Sequence={6,15,21,33,....,159,175,177,...,
    
Is this an interesting sequence or not? If I want yes it is,
if I want no it 
is not.
---------
PS1
Control of the number exotic among 3p numbers
Phi[175]=120, Sigma[175]=248 
so 2*120-240+8=0
----------
PS2
By the way:   
Can you find the next number after 175 which is not
of 3p form? If exists at all.
