While I don't speak directly for the developer of vmsACARS (who is also the developer of phpVMS) - I wouldn't say support for vmsACARS v1 ended, but further development of v1 has stopped. Likewise, minor fixes for issues in v1 are unlikely as v2 is presently in the alpha phase. Hoping v2 sees beta phase soon. V2 isn't stable enough for production use at present.
The issue you have experienced in v1 has only affected a very small number of users. But we do need input on the issue - as @DisposableHero indicated - to check it against the v2 alpha releases.
As for the anti-spam, it's a necessary evil. It can be a pain at times.
