Some people do, I don't.
Webmoney seems to work well for those who are not American (as the US blocks Webmoney) and for those who don't earn much.
I looked into it briefly, I think if you want to send/receive more than like $100 a month then you need to provide a passport to Webmoney for ID, at which the limit is like $1000 a month. <- These limits are just a guess off the top of my head, I'm sure they're wrong but the limits are something like that.
Then, once you've received the Webmoney payment you have to them pay a 3rd party individual a percentage to convert it to something usable such as PayPal. From what I hear, most of these 3rd party converters are sketchy and are nothing more than some local person who provided enough identification documentation to Webmoney to be able to perform these transactions for Webmoney users.
I really don't know much about Webmoney other than the simple fact that it is 100% a total waste of time for Americans to consider...
My suggestion is if you are a half way decent affiliate then to just stick to bank wires, and if your a noob to patiently use PayPal (if its available as a payout option to affiliates).

Even though this file deletion started yesterday for me too at least for now seem to be files that have been inactive(no downloads) for sometime,maybe 45 days? and even though i haven't gotten an answer yet as to why exactly the files are been deleted, that is what it looks to me, deletion of inactive files, since i never learned how long Xerver it's supposed to keep inactive files before deletion at least for now if a file that hasn't been touch in 6 weeks it's deleted it doesn't bother me too much, as long as what i think it's the reason for the deletion and not some last minute changes in their TOS.
I don't see any documented retention policy on their TOS or Affiliates pages. They're most likely too new of a file host to make that determination at this point in time.
45 day retention is pretty average AFAIK for file hosts. You have to consider how many neophytes upload terabytes of data to a file host and never even post the DDL links anywhere, and this costs the file hosts a tremendous amount of money to have to combat....
