why would anyone do that?
If you weren't around for Round 1 of this game, you aren't aware of SGP's reputation for doggedly tracking those who dare disinfect their virii. SGP was a group both to fear and respect. SGP claimed server groups as their exclusive territory and publicly posted them to let people know what they were in for if they disinfected or captured the virii there.
Conversely, SGP was dormant during Round 2. We suspect that person or persons currently undisclosed attempted to use SGP's reputation even during that round to inspire fear by creating the rumor that SGP was still around. While it was still around, it was not actively attacking or acting as a group. Members joined other groups and formed their own groups. All this was prior to the group update as well. We kept in contact nevertheless.
The SGP tag used to inspire fear and awe in players, nowadays it seems like the tag is vulgarly used by others to scare people, much like the bogeyman. "Don't mess with this virus or SGP will get you!"
Because of attacks on SGP's servers and the theft of our software as well as the profane use of the SGP tag on other software, the SGP tag is ubiquitous right now. SGP doesn't mind sharing software. SGP does mind its name being misused.
