Hello and a continued welcome to the THF!
We are, as all forums, slammed with spam memberships and are now actively trying to do something about it. There is no easy single answer even with the finest spam software available. It is possible that a membership could get caught in the crossfire of an IP that produces spam members. It is therefore also possible that when we delete that IP a member could get caught up in that and disappear with the IP. That is the worst case scenario but it happens. We are doing everything we can to prevent that.
There are also other factors that can cause loss of membership and/or loss of information and posts. Computers and the information they contain ... and the way they work is tricky on the very best day.
So, please, do not use the forum as a "primary" source or storage. Always back up your work, your comments (if needed) to your personal computer or external hard drives etc. This will help prevent a major situation for you in case something goes awry here. It would also be the prudent approach to any and all forums that you belong to.
If there is a problem that arises, please email us immediately so that we can help you fix it.
