tl;dr: sadly they all have serious problems
springrts.fr downloads are old:
Offers Spring 95.0 - current is 96.0
Offers Springlobby 0.169 - current is ~0.180
"Dernière version de Balanced Annihilation 7.84," - current version is BA 7.91
(For wanting to be a site about spring it also seems quite "BA-heavy.")
Another example, BA webpage was offering old game version for months ( http://springrts.com/phpbb/viewtopic.php?f=44&t=31623 )
On moddb the latest news on engine is "Spring 0.82.7 bug fix release" and if you click it, then you end up here: http://sourceforge.net/projects/springr ... e/download
Downloading an 3 year old version without any clue that it is totally useless.
https://plus.google.com/+Springrtsengine
Does not give good impression of spring either.
For example it links to these games:
Zero K
Evolution RTS
Gundam RTS
Conflict Terra
Spring: 1944
That is neither up to date nor complete list.
http://sourceforge.net/projects/springrts/
Offers old 95.0 on front page: 828 Downloads (This Week)
828 people per week for whom playing will work...
Just some examples, there are many more.
Just fixing some links now will not be enough, they would just outdate in little time, the problem is deeper:
Those sites/profiles never get maintained and always collect outdated news, spam and dead links.
In least worse case, one or two people regulary use the site: But then the content only shows their projects (or their interessts) rather than representing whole spring.
It is not a matter of:
"if you want more news on the moddb spring profile then just post some"
or
"If you want to help people on spring facebook with bugs then just post there"
or
"If you want your game on google+ then just add it"
This way every time someone creates a new page or profile on social media it forces other people to also waste effort on it.
The past and present show that does work.

If someone makes a mod/lobby/anything then it must not be that he is basically "forced" to represent it on so many different sites.
Last years have shown spring peoplepersons can not spread so thin across multiple places, otherwise we would not have dead profiles like the moddb one etc.
Spring peoplepersons can NOT update 3 different image galleries, can NOT maintain 4 different list of games and can NOT provide help with bugs in 5 different forums.
It is nice that some people want to help by making sites/profiles but examples like above do more harm than good.
Suggestion:
1) Do not spawn more spring engine sites or profiles.
2) On existing spring sites/profiles remove everything. Put a spring logo, put a note "Go to springrts.com for all spring needs"
Make it clear that this page is unofficial, any downloads that might be found do not work and that noone will provide support.
3) If you want to make a site about your game, then make a site about your game. Do not try to represent other games or spring itself, it will not do them justice.
