I am also getting frustrated with numerous merge requests with only gedcoms and no resources.
I have had people send me 10-15, or more, merge requests on a familyline at one time. These requests often come with mixed up lineages - sons being their fathers - father, or sons being married to their own mother etc. Or mixed siblings. Or extra siblings with no confirmation of relationship.
When I ask the requestee - have you checked these for accuracy with your actual sources the answer is often
NO,
or it's not my gedcom, it's my family members data,
or I found it's just too tedious to enter or verify sources
or I don't have time for that, this is just a casual past time
or -the worst - just - you do it.
(Sometimes I get the impression that they think I 'work' here and this is my full-time job!)
When I ask if they will be doing the clean-up after the merge, the answer again is often
"no, you do it.'
For each person there are often parents, spouses, siblings, children - all needing to be checked, compared, verified etc. So one merge request multiplies exponentially.
I have finally come up with 'my' answer for requested merges from people who aren't really cooperating in any manner other than a merge request. It is:
Hello. I enter data on my family lineages as I have the time, which varies greatly. I don't always have complete data entered on collateral lines, so I may or may not have related resources somewhere. Althought these appear they might be the same person, it's difficult to compare without any details from your end. I will mark this person as an unmerged match, and when you have completed verifying the data and entered it, let me know so we can compare them again and then we complete the merge."
And some people are truly dedicated to merging, verifying, confirming, adding sources - those I go out of my way to complete the merge - even if I have to go find the sources somewhere in the piles of paper!
