Skrill was never available for depositing/withdrawing money in MQL5.com.
Previously Neteller was available and then later Skrill was also added and infact both were available in 2017.
I remember Netellet, but not Skrill, you may be right.
that's ok, so is there any chance that Neteller or Skrill could be available again?
That's up to MQL5.com, but I don't think its in their plans.
